A new and improved skate light apparatus which includes a self-contained, battery-powered light assembly and either an adjustable bracket or an adjustable strap for connecting the light assembly to the skate. The light assembly includes a housing, a battery pack, a light source, and a switch connected between the battery pack and the light source. In addition, the light assembly may also include a rotatable reflector and an electric motor for rotating the reflector. The adjustable bracket which supports the light assembly is connected to support structures, such as struts or studs, on the skate. When a strap is used to attach the light assembly to the skate, the light assembly housing includes a slot for receiving an adjustable strap, and the adjustable strap is threaded through the slot and extends around the foot on which the skate is fitted. The adjustable strap can include hook material and complementary loop material for securing the adjustment of the strap around the foot. The light assembly can further include a sound generator, such as a tone generator. The light that is emitted from the light source can be a flashing light. In this respect, electronic circuitry can be provided to cause the light source to flash.

A radiation image generating system for providing planar and tomographic views of portions of a patient's anatomy for use in radiation therapy procedures comprises a fluoroscopic simulator apparatus having a radiation source; a computer system for acquisition and processing of radiation transmission images; a manual input; display and storage devices for such images; means for simulation of an irradiation beam; and, apparatus for the cutting of blocker contour templates, blocker patterns and blockers. The system provides planar transmission images and tomographic views associated and correlated therewith. The system's radiation image detecting means includes an area solid state camera having a planar detector array that is cooled below ambient temperatures. The system further includes means for passively converting radiation transmission images into light images for detection by the camera. The system and method of the invention can provide a plurality of tomographic views from a rotational scan of the patient and it can provide three-dimensional in-depth views that can be displayed also while being rotated about an axis.

Radiation image generating system and method

A linear detector selectively detects successive line images from different angles while the linear detector and a radiation source are rotated about a patient. Radiation-transmission images are generated and detected and converted to computer-grabbed images by a computer which acquires, processes, stores and reconstructs the images. A visual monitor display reconstructs video images including a planar image and tomographic images representing sections orthogonal to the planar image. Selectively-positionable field-delineating lines corresponding to intersectional outlines between a simulation beam and the planar image are overlaid on the planar image. Beam-delineating lines are updated by the computer to correspond to intersectional outlines as the field-delineating lines are positioned.

X-ray imaging system with a sweeping linear detector

A simulation/generation/verification system for blocker patterns and blockers for use in radiation therapy comprises a fluoroscopic simulator apparatus, a computer system for acquisition and processing of fluoroscopic images, a manual input device for superposing blocker pattern outlines onto such images, display and storage devices for such images, apparatus for automatic cutting of blocker contour templates, blocker patterns and blockers, and apparatus for verification thereof. The system also facilitates acquisition of compensator contours and generation of corresponding compensator filters for incorporation with blockers. The system facilitates simulation, generation, and verification of blocker patterns or blockers per se in one substantially continuous procedure that minimizes intervening manual steps, while a patient is aligned within the system during an uninterrupted session. Computer-aided and computer-controlled fluoroscope image composition, linearization, enhancement and manipulation, marking of target field, acquisition and appropriate manipulation and superposition of compensator contour information, recording of all of such information and use thereof for automatic cutting of blocker contour templates, compensator filters, blocker patterns or blockers and immediate verification thereof facilitate time and cost savings, improvement in blocker accuracy, and reduction of patient anxiety and discomfort.

Method and apparatus for generating radiation blockers

A tomographic x-ray machine has camera and film-plane sections which move about a primary axis for imaging a selected cross-section of an anatomical member onto a film. A 'scout image' of the member is obtained at right angles to the plane of the desired cross-section to indicate the cross-section's orientation with respect to the primary axis. The anatomical member is then moved to place it on the primary axis and a second film is located at the same angle that the selected cross-section makes with the primary axis. The second film and the cross-section are then maintained in parallel planes throughout motion of the camera and the second film during tomographic radiography.

Tomographic method and apparatus

Disclosed herein is an air line lubricator safety device for automatically actuating an air actuatable member located outside of the lubricator. The air actuatable member may be a normally open air valve in an air line leading to an air operated tool, said air valve being automatically closed when the oil level in the lubricator falls below a predetermined level and thereby prevents operation of the tool; or the air actuatable member may be a signal device such as a whistle or light or other signal automatically air actuated when the oil level in the lubricator falls below a predetermined level. The safety device comprises a lubricator having an oil bowl containing oil and air under pressure, the bowl having a head provided with a piston chamber, a float-controlled piston slidable in the chamber, an air intake passage in the head communicating with the pressurized area region of the bowl and with the piston chamber, and an air oulet tube leading from the piston chamber; said piston moving downwardly in the chamber when the oil supply falls below a predetermined level, thereby permitting pressurized air to flow through the air outlet tube for actuating one of the air actuatable members located outside of the lubricator.

Air line lubricator safety device

Disclosed herein is a signal device for detecting the condition of a fluid line filter and automatically activating a signal indicating that the filter requires cleaning or replacement. The signal device may be built in or installed as an attachment in the fluid lines leading to and from a filter for removing moisture and/or contaminants from the line. The signal device comprises a piston housing containing a piston movable to signalling position in response to reduced fluid pressure adjacent one end of the piston resulting from reduced volume of fluid passing through the filter, locking means for retaining the piston in said signalling position, and signal actuating means activated by fluid pressure when the piston is in said signalling position. The signal may be visual or audible, actuated mechanically or electrically.
