Abstract: A position detector includes a source of radiant energy, such as infrared light. A sensor is spaced from the source. The source and the sensor can be carried spaced apart from one another by a housing. Control circuits, carried by the housing, are coupled to the source and the sensor. Pulsed radiant energy, emitted by the source is incident on the sensor only when transmitted by a solid optical medium which has a predetermined orientation relative to the housing. When the medium has the predetermined orientation, the sensor receives transmitted radiant energy from the source. When the medium moves from the predetermined orientation, the sensor ceases to receive the transmitted radiant energy from the source, and the control circuits can generate an alarm indication.

Abstract: Photodetectors operable to achieve multiplication of photogenerated carriers at ultralow voltages. Embodiments include a first p-i-n semiconductor junction combined with a second p-i-n semiconductor junction to form a monolithic photodetector having at least three terminals. The two p-i-n structures may share either the p-type region or the n-type region as a first terminal. Regions of the two p-i-n structures doped complementary to that of the shared terminal form second and third terminals so that the first and second p-i-n structures are operable in parallel. A multiplication region of the first p-i-n structure is to multiply charge carriers photogenerated within an absorption region of the second p-i-n structure with voltage drops between the shared first terminal and each of the second and third terminals being noncumulative.

Abstract: A medical pump including an electromagnetic emitter and detector is provided. The emitter emits electromagnetic radiation of a predetermined wavelength. A pump set that is compatible with the medical pump modifies the emitted electromagnetic radiation when properly installed in the pump. The detector receives electromagnetic radiation, and a filter excludes electromagnetic radiation having a wavelength other than the predetermined wavelength. The pump monitors the filtered signal to determine whether the received electromagnetic radiation corresponds to the emitted electromagnetic radiation as modified by a properly loaded, compatible pump set and determines whether a compatible pump set is properly loaded in the pump as a function thereof.
