  • Patent number: 9967908
    Abstract: In a direct mode two-way radio frequency communications system having a plurality of direct mode traffic channels, a first direct mode subscriber unit (DMSU) monitors a preconfigured direct mode control channel (DMCC), the DMCC being a channel that is monitored by all DMSUs that are idle in the system, and which is time divided into slots including traffic channel status slots (TCSSs), each TCSS associated with another physical direct mode traffic channel (DMTC) in the communication system. Responsive to detecting a request to initiate a new call, the DMSU selects a first DMTC on which to transmit the call, transmits during the next TCSS of the DMCC associated with the selected DMTC a header indicating the first DMSU's intention to transmit a new call on the selected DMTC, and subsequently switches to the selected DMTC and transmits the new call.

  • Patent number: 9654939
    Abstract: A radio receives a call including a call include bitmask (CIB). The radio retrieves a call include list (CIL) that, for each bit position in the CIB, maps the bit position to one of a radio identifier, a talk group identifier, and a sub-CIL. The radio determines that one bit position in the CIB is set to a value indicating that a radio associated with a radio identifier mapped to the bit position in the CIB via the CIL or to a talk group identifier mapped to the bit position in the CIB via the CIL are to be included in the call. The radio matches its identifier to the radio identifier mapped to the bit position or matches a talk group to which it subscribes to the talk group identifier mapped to the at least one bit position and unmutes the call.

  • Publication number: 20080047359
    Abstract: This DigiFlux™ digital gas flow sensor (DigiFlux™) can measure the gas flow by its Hall effect gas sensor. DigiFlux™ [FIG. 1] is based on the Hall effect. In DigiFlux™, an air-float with a small magnetic-iron attached to its bottom, is upright on a Hall effect sensor made by a conductor with I/O connector. When the air-float moves up or down caused by the gas influx pressure, the magnetic-iron in the bottom of air-float will cause electromagnetic sense, and will generate Hall voltage (Vh) signal on Hall effect sensor. The Vh signal will be sent to amplifier then to the MCU/DSP for analog-to-digital conversion, then the gas influx flow will be sensed as digital signal and can be processed by MCU/DSP. Based on functional program one can set different modes to measure gas flow. DigiFlux™ can measure gas flow with high-precision even with a small influx of gas.

  • Publication number: 20080031506
    Abstract: A method of characterizing a mass within a digital mammogram. A region of interest is identified that includes the mass and surrounding tissue. A border outline of the mass is identified. A rectangular image is formed wherein each column of the image is formed by repetition of steps. A vector is employed for each of a set of ray angles, wherein the vector extends from a central point of the mass and intersects the border outline at an intersection point. A starting pixel along the vector is identified, between the intersection point and the central point, at a first distance before the intersection point. An ending pixel along the vector is identified at a second distance beyond the intersection point. Pixels along the vector, from the starting pixel to the ending pixel, are remapped as the respective column in the rectangular image. Texture features are extracted from the formed rectangular image.
