Abstract: An optical sensing module suitable for wearable devices, the optical sensing module comprising: a silicon or silicon nitride transmitter photonic integrated circuit (PIC), the transmitter PIC comprising: a plurality of lasers, each laser of the plurality of lasers operating at a wavelength that is different from the wavelength of the others; an optical manipulation region, the optical manipulation region comprising one or more of: an optical modulator, optical multiplexer (MUX); and additional optical manipulation elements; and one or more optical outputs for light originating from the plurality of lasers.

Abstract: A radio access system comprises a base station and a plurality of subscriber locations. The subscriber locations each comprise a residential base unit or subscriber interface which includes line termination equipment. A group of subscribers is served by a pool of residential radio transceiver units in radio communication with the base station which is connected to the residential base units by a shared bus. A group of subscriber locations may be served by a lesser number of residential transceiver units, while at the same time providing individual locations with access to increased bandwidth for ISDN services and the like. Also described is a system in which a subscriber's base unit is connected to two or more residential transceiver units to allow increased bandwidth without requiring additional residential base units.

Abstract: A deviation meter, responding to a deviation signal, is mounted on a turntable which rotates in response to a set point adjustment. Rotation of the turntable maintains the null position of the deviation meter pointer at a scale position corresponding to a set point value, so that a direct readout of the actual measurement value is provided.
