Abstract: Presented herein are techniques to allocate use of controlled wireless spectrum. A method includes receiving, from a wireless local area network service provider, a request for wireless local area network spectrum for a future time window, wherein the wireless local area network spectrum is subject to automated frequency coordination, in response to the request, sending, to an incumbent that uses the wireless local area network spectrum, a query consistent with the request for the wireless local area network spectrum for the future time window, receiving, from the incumbent, in response to the query, a grant to use the wireless local area network spectrum for the future time window, and in response to receiving the grant, sending permission to the wireless local area network service provider to use the wireless local area network spectrum for the future time window.

Abstract: Presented herein are techniques to optimize wireless local area network access point beam settings. A method includes, during a survey period, causing a first access point and a second access point in a wireless local area network, to simultaneously transmit survey transmissions according to a predetermined sequence of transmission states, receiving, from a survey station that received the survey transmissions during the survey period, telemetry associated with the survey transmissions, the telemetry including a location of the survey station when the survey station received the survey transmissions, and after the survey period, controlling, based on the telemetry associated with the survey transmissions, the first access point to operate according to a first transmission state from among the transmission states and the second access point to operate according to a second transmission state from among the transmission states.

Abstract: Techniques herein facilitate dynamic configuration of a wireless local area network (WLAN) for large public venue (LPV) environments. In one example, a method may include providing an initial configuration for access points APs of a WLAN for an event at an LPV based on a profile for the event, a location of each AP for the venue, and anticipated demand at the APs; determining, for a particular time for the event, a distribution of wireless devices and channel support capabilities of the wireless devices different locations for the LPV; and providing an updated configuration for one or more APs at the one or more locations for the venue based on the distribution of the wireless devices and the channel support capabilities of the wireless devices determined for the particular time for the event at the LPV.

Abstract: A method for providing adaptive radio transmit power based on antenna pattern and elevation tilt measured through an accelerometer is provided. The method includes estimating an orientation of a wireless device using an orientation sensor integrated in or on the wireless device, and determining an adjustment factor for a transmitter of the wireless device based on the orientation. The method further includes adjusting output power of the transmitter of the wireless device based on the adjustment factor.

Abstract: A method for calibrating a magnetometer of a device is provided. The method includes collecting, with a portable calibration device having a magnetometer, magnetic field measurements in a spatial region about a mounting location where the device is to be installed for operation, estimating magnetometer compensation parameters to correct for magnetic field distortion at the mounting location based on the magnetic field measurements collected by the portable calibration device, and configuring the device installed at the mounting location based on the magnetometer compensation parameters.

Abstract: A roll assembly temperature sensing system for a pellet mill includes: a thermal sensor (160); and a pellet mill roll assembly rotatably disposed in a rotor assembly. The pellet mill roll (140) assembly includes: a roll shaft; a bearing disposed circumferentially around the roll shaft; and a seal (150) disposed between an end of the bearing and the rotor assembly. The rotor assembly includes an area defining a die cavity adjacent to the seal (150). The thermal sensor (160) is disposed within the die cavity, and is configured to detect a temperature of the seal resulting from heat conducted from the bearing.

Abstract: A reciprocating gas compressor valve having a plurality of clusters of kidney shaped holes positioned along a common circular or annular locus in the main body and a sealing element with a top portion, a bottom portion and a tubular section. The tubular section is integrally connected to the top portion and bottom portion. In an open position, a flow pathway is provided through the clusters of kidney shaped holes and the tubular section and the bottom profile abuts a stop surface of the valve. In a closed position, the top profile abuts the seat for sealing gas flow within the valve.

Abstract: A piezoelectric sensing device is described for measuring material thickness of target such as pipes, tubes, and other conduits that carry fluids. The piezoelectric sensing device comprises a substrate such as a flexible circuit material, a piezoceramic element, and a solder layer disposed therebetween. These features are arranged in manner that provides a low-profile measurement device suitable for high-temperature applications such as those applications in which the temperature exceeds 120° C. Embodiments of the piezoelectric sensing device can be configured for use as stand-alone units separately located on the target or for use as a string of sensing elements coupled together by way of the flexible circuit material.
