Abstract: The present disclosure relates to broadcasting multiple packets at periodic intervals for receipt by other devices. A common device can transmit multiple beacon protocols simultaneously (i.e., an interleaving of different beacons), such that regardless of which protocol a receiving device supports, it may utilize advertisements from that common device (e.g., beacon). Thus, a single or common transmitting device may support multiple advertisements, such that the amount of hardware to be deployed in any network is reduced. Rather than deploying a device per beacon, a single device may be deployed and transmit multiple beacons.

Abstract: A long range millimeter wave imaging radar system. Preferred embodiments are positioned to detect foreign object debris objects on surface of the runway, taxiways and other areas of interest. The system includes electronics adapted to produce millimeter wave radiation scanned over a frequency range of a few gigahertz. The scanned millimeter wave radiation is broadcast through a frequency scanned antenna to produce a narrow scanned transmit beam in a first scanned direction (such as the vertical direction) defining a narrow, approximately one dimensional, electronically scanned field of view corresponding to the scanned millimeter wave frequencies. The antenna is mechanically pivoted or scanned in a second scanned direction perpendicular to the first scanned direction so as to define a two-dimensional field of view.

Abstract: Pixel circuits, capable of operating in either “snapshot” or “rolling integration” mode, and compatible with a conformal photodiode coating. Preferred embodiments of the present invention are compatible with these coating materials, as well as others, including amorphous Silicon. The preferred pixel circuits includes additional transistors not provided in prior art pixel circuits to divert leakage current away from integration nodes when not integrating, to reset the integration node, and to buffer and select the integrated voltage.

Abstract: A CMOS image sensor with a many million pixel count. Applicants have developed techniques for combining its continuous layer photodiode CMOS sensor technology with CMOS integrated circuit lithography stitching techniques to provide digital cameras with an almost unlimited number of pixels. A preferred CMOS stitching technique exploits the precise alignment accuracy of CMOS stepper processes by using specialized mask sets to repeatedly produce a single pixel array pattern many times on a single silicon wafer with no pixel array discontinuities. The single array patterns are stitched together lithographically to form a pixel array of many million pixels. A continuous multilayer photodiode layer is deposited over the top of the many million pixel array to provide a many million pixel sensor with a fill factor of 100 percent or substantially 100 percent.

Abstract: An optical cross connect switch. In this switch any optical fiber in an input set of optical fibers, each carrying a communication beam, can be cross connected to any optical fiber in an output set of optical fibers. An alignment beam is added to and aligned co-axially with the communication beam carried by each fiber in the input set of optical fibers to define a communication-alignment beam for each fiber. Each communication-alignment beam is directed within a confined optical pathway to a specific exit aperture in an input array structure. The exit apertures for all of the communication-alignment beams are arranged in a pattern defining an input array so that each communication-alignment beam can be identified by the location of its exit aperture in the input array structure. Each communication-alignment beam is formed into a cross-connection beam by a micro-lens in a first lens micro-lens array.

Abstract: A flow monitor that is purely optical and non-invasive and does not possess any significant obstruction to the flow. It creates no significant pressure drop and no pulsed pressure waves in the patient's airway and can be placed close to the patient, it is not sensitive to gas composition and contamination, it is easy to clean, because it uses a disposable or reusable flow measurement cuvette, and it is more accurate, rugged and reliable than existing sensors on the market. Fluid flow is determined by optically monitoring the time of travel of a disturbance in the fluid flow. In one embodiment, the disturbance is caused by heating the fluid and in another embodiment, the disturbance in air flow is caused by injecting minute drops of water into the flowing air.
