Abstract: A sensory substitution device according to an embodiment of the invention includes a thermal imaging array for sensing thermal characteristics of an external scene. The device includes a visual prosthesis adapted to receive input based on the scene sensed by the thermal imaging array and to convey information based on the scene to a user of the sensing device. The visual prosthesis is adapted to simultaneously convey to the user different visual information corresponding to portions of the scene having different thermal characteristics. One type of thermal imaging array includes a microbolometer imaging array, and one type of visual prosthesis includes a retinal implant. According to additional embodiments, an apparatus for obtaining thermal data includes a thermal detector adapted to sense thermal characteristics of an environment using a plurality of pixels.

Abstract: Endoscope apparatus and methods provide measurements of infrared radiation in the 2 to 14 micrometer wavelength range by mounting an array of infrared radiation detecting elements at the distal end of the endoscope, according to aspects of the invention. Sensor packaging techniques and elemental distributions for the sensor array provide additional advantages.

Abstract: An electrocardiograph for connection to sensors outputting analog electrical signals and having at least one sensor outputting electrical signals is provided. At least one of the analog signals is sampled, converted from analog to digital form and stored in a memory means. A processor writes consecutively sampled digitalized signals represented by a predetermined duration of the analog sensor output signal to addresses of the memory for storage in consecutive order. The processor applies the stored data from the addresses in consecutive order through a printer which prints a series of portions of a curve representative of the analog signal to produce a cardiogram extending in the direction of advance of the print medium. A magnetic tape cassette is provided for storage of data and an audible alarm means is also provided. The memory may also store programs for analysing the data.
