Saw II later reveals these missing pieces have been intended to show the missing survival instinct of Jigsaw's victims. At one of the crime scenes, Tapp and his partner, Steven Sing, discover a penlight with fingerprints on it. Forensics indicate that the fingerprints belong to Dr. Lawrence Gordon, who is taken to the police station for questioning. Saw V later revealed that Jigsaw accomplice Mark Hoffman had planted this penlight to arise suspicion on Gordon.

The cornea is required to be transparent to transmit light to the retina. Because of injury, infection or inflammation, an area of opacity may develop which can be seen with a penlight or slit lamp. In rare instances, this opacity is congenital. In some, there is a family history of corneal growth disorders which may be progressive with age.

Clinicians routinely check the pupils of critically injured and ill patients to monitor neurological status. However, manual pupil measurements (performed using a penlight or ophthalmoscope) have been shown to be subjective, inaccurate, and not repeatable or consistent.Olson DM, Stutzman S, Saju C, Wilson M, Zhao W, Aiyagari V. Interrater reliability of pupillary assessments. Neurocrit Care. 2016;24(2):251-257.

Medical halogen penlight to observe pupillary light reflex Halogen headlamps are used in many automobiles. Halogen floodlights for outdoor lighting systems as well as for watercraft are also manufactured for commercial and recreational use. They are now also used in desktop lamps. Tungsten-halogen lamps are frequently used as a near-infrared light source in Infrared spectroscopy.

For an adequate test, vision must not be entirely lost. In dim room light, the examiner notes the size of the pupils. The patient is asked to gaze into the distance, and the examiner swings the beam of a penlight back and forth from one pupil to the other, and observes the size of pupils and reaction in the eye that is lit.

To check the oral mucosa, the patient's cheek is exposed with a tongue depressor and the tissues inspected with a penlight. Healthy tissue appears moist, smooth, shiny and pink. Stensen's duct is opposite the second molar. Abnormal findings include dryness, cyanosis, paleness and Fordyce spots, and signs of disease include canker sores, Koplik's spots (an early indication of measles), candidiasis and leukoplakia.

The patient tilts their head back and opens their mouth for the hard-palate assessment. Visual inspection with a penlight shows a healthy palate as whitish in color, with a firm texture and irregular transverse rugae. Abnormal findings include yellowness or extreme pallor, and diseases include torus palatinus, cleft palate, submucous cleft palate, High-arched palate, Kaposi's sarcoma and leukoplakia.

Hemoscrotum can follow trauma (such as a straddle injury) or can be a complication of surgery. It is often accompanied by testicular pain. It has been reported in patients with hemophilia and following catheterization of the femoral artery. If the diagnosis is not clinically evident, transillumination (with a penlight against the scrotum) will show a non-translucent fluid inside the scrotum.

Light painting made by spinning burning steel wool in an enclosed space There are five basic types of light painting or light drawing: Historically they have just been lumped into a category called light painting, there are subclasses of the different ways you can use a light recorder (aka camera) to make photographs of just light or adding subject matter into a light painting or light drawing. A distinction can be made between light painting and light drawings or subgroups of this type of work; # Picasso's classic light drawing with a penlight published in Life magazine circa the 1960s. # Light painting the subject in a totally dark room with a camera on a tripod, open the camera up and paint light onto the subject with a light source generally a small penlight. # Long exposure with a camera fixed on a tripod.

73-82% of all ocular injuries resulting from mine explosions are due to fragmentation of shrapnel upon detonation, so gross anatomical inspection by penlight may not rule out open globe injury. Harlan JB, Pieramici DJ. Evaluation of patients with ocular trauma. Ophthalmol Clin North Am. 2002; 15(2):153-61./ref> Computerized tomography (CT) may detect foreign matter and aid the clinician in determining the presence of an open-globe injury.

In Saw V, a memorial service is held for the deceased officers from the Jigsaw murders. Tapp's police picture is among the pictures of the deceased officers. Tapp also appears in a flashback, inquiring Dr. Lawrence Gordon about the penlight Mark Hoffman planted. Danny Glover was originally set to make a cameo appearance as David Tapp in Saw V, but could not show up due to scheduling issues.

Example of light painting In this technique, a scene is kept very dark and the photographer or an assistant takes a light source—it can be small penlight—and moves it about in patterns. The light source can be turned off between strokes. Often, stationary objects in the scene are illuminated by briefly turning on studio lights, by one or more flashes from a strobe light, or by increasing the aperture.Greenspun, Philip (January 2007).

The soft palate is checked with a penlight. It should be light pink, smooth and upwardly movable. To check the uvula, a tongue blade is pressed down on the patient's tongue and the patient is asked to say "ah"; the uvula should look like a pendant in the midline and rise along the soft palate. Abnormal findings include deviation of the uvula from the midline, an asymmetrical rise of the soft palate or uvula and redness of either.

In veterinary practice, nuclear sclerosis is a consistent finding in dogs greater than six years old. Nuclear sclerosis appears as a bilateral bluish-grey haziness at the nucleus, or center of the lens, caused by an increase in the refractive index of that part of the lens due to its increased density. It is often confused with cataracts. The condition is differentiated from a cataract by its appearance and by shining a penlight into the eye.

NiMH batteries have replaced NiCd for many roles, notably small rechargeable batteries. NiMH batteries are commonly available in AA (penlight-size) batteries. These have nominal charge capacities (C) of 1.1–2.8 Ah at 1.2 V, measured at the rate that discharges the cell in 5 hours. Useful discharge capacity is a decreasing function of the discharge rate, but up to a rate of around 1×C (full discharge in 1 hour), it does not differ significantly from the nominal capacity.

Reflex - PLR Analyzer results screen for iOS (brightlamp, Inc.) Traditionally, pupil measurements have been performed in a subjective manner by using a penlight or flashlight to manually evaluate pupil reactivity and using a pupil gauge to estimate pupil size. However, manual pupillary assessment is subject to significant inaccuracies and inconsistencies. Studies have shown inter- examiner disagreement in the manual evaluation of pupillary reaction to be as high as 39 percent.Olson D, Stutzman S, Saju C, Wilson M, Zhao W, Aiyagari V. Interrater reliability of pupillary assessments.

The reflector may have a flat transparent cover to keep out dirt and moisture, but some designs have a plastic or glass "bulls-eye" lens to form a concentrated beam. The lens or reflector cover must resist impacts and the heat of the lamp, and must not lose too much of the transmitted light to reflection or absorption. Very small flashlights may not have a reflector or lens separate from the lamp. Some types of penlight bulbs or small LEDs have a built-in lens.

For example, the Waterlow score and the Braden scale deals with a patient's risk of developing a Pressure ulcer (decubitus ulcer), the Glasgow Coma Scale measures the conscious state of a person, and various pain scales exist to assess the "fifth vital sign". The use of medical equipment is routinely employed to conduct a nursing assessment. These include, the otoscope, thermometer, stethoscope, penlight, sphygmomanometer, bladder scanner, speculum, and eye charts. Besides the interviewing process, the nursing assessment utilizes certain techniques to collect information such as observation, auscultation, palpation and percussion.

Although electrical devices that create a heated probe may be used for the cauterization of tissue in some applications, electrosurgery refers to a different method than electrocautery. Electrocautery uses heat conduction from a probe heated to a high temperature by a direct electrical current (much in the manner of a soldering iron). This may be accomplished by direct current from dry-cells in a penlight-type device. Electrosurgery, by contrast, uses radio frequency (RF) alternating current to heat the tissue by RF induced intracellular oscillation of ionized molecules that result in an elevation of intracellular temperature.

Fixation targets are required for both the near (33 cm) and far (6m) components of the cover test. Near Targets (33 cm) Light source – A penlight/light from retinoscope or ophthalmoscope could be used at the start of the near cover test assessment to observe the patient's corneal reflections, and to see whether their fixation is steady, central and maintained. Assessing the patient's fixation is especially important in those patients who suffer from amblyopia. Detailed target – Any small object that has the ability to stimulate Accommodation (eye) and allow the examiner to assess the patient's fixation.
|
|
Frequently, during testing, the cover can be removed prematurely; therefore, as mentioned earlier, dissociation of at least three seconds is needed for the patient to take up fixation during cover testing. This time allows for patients to recover from dissociation post cover removal. A penlight should be used to observe the steadiness and positioning of the deviated eye. Ensure to assist the patient in maintaining fixation on accommodative or distance targets at all times - if testing on children or adults, request specific details pertaining to the accommodative target (to assure accommodation is utilized) for near testing.

The exact terminal voltage, capacity and practical discharge rates depend on cell chemistry; however, devices designed for AA cells will usually only take 1.2-1.5 V unless specified by the manufacturer. Introduced in 1907 by The American Ever Ready Company, the AA battery size was standardized by the American National Standards Institute (ANSI) in 1947, but it had been in use in flashlights and electrical novelties before formal standardization. ANSI and IEC Battery nomenclature gives several designations for cells in this size, depending on cell features and chemistry. Due to their popularity in small flashlights, they are often called "penlight batteries".

Five months ago, Gordon, while discussing the terminal brain cancer of patient John Kramer, was interrogated by Detectives David Tapp and Steven Sing, who found his penlight at the scene of one of Jigsaw's games. Gordon's alibi cleared him, but he agreed to view the testimony of heroin addict Amanda Young, the only known survivor of one of Jigsaw's traps. After Gordon was released, Tapp and Sing found Jigsaw's warehouse using the videotape from Amanda's game. There, they apprehended Jigsaw and saved a man from a trap, but Jigsaw escaped after Sing triggered a shotgun trap in the hallway that killed him.

Considering them conceptually, Leah Ollman wrote, "Throughout this body of work, the paper's surface does double duty as object and subject, material and image. The literal and the abstract merge." Carey's "Caesura" series (2016–18) features vertical breaks in color along central axes with fine, radiating vein-like fissures that she creates by creasing or accordion-folding the paper. The "Dings & Shadows" series (2010– ) introduces greater compositional range with dense surfaces of wrinkles and crumples ("dings") occurring at all angles, which Carey draws out with a penlight to create shadow and depth; she has often exhibited them in installations of up to twenty panels.

In the late 1930s, Norm Krim, then an engineer for Raytheon, was looking into subminiature tubes for use in consumer applications such as hearing aids and pocket radios. Krim's team developed the CK501X subminiature amplifier tube that could run on penlight A type batteries or small 22.5 V B type batteries. Following World War Two, Krim was interested in developing the first pocket vacuum tube radio. Raytheon approved, and a team headed by Krim designed a set of subminiature tubes specifically for radios (2E32, 2E36, 2E42 and 2G22). Raytheon’s acquisition of Belmont Radio proved prescient, and the result was the Belmont Boulevard in 1945.

Cranial nerves III, IV, and VI are usually tested together as part of the cranial nerve examination. The examiner typically instructs the patient to hold his head still and follow only with the eyes a finger or penlight that circumscribes a large "H" in front of the patient. By observing the eye movement and eyelids, the examiner is able to obtain more information about the extraocular muscles, the levator palpebrae superioris muscle, and cranial nerves III, IV, and VI. Loss of function of any of the eye muscles results in ophthalmoparesis. Since the oculomotor nerve controls most of the eye muscles, it may be easier to detect damage to it.
