An example apparatus for determining a precise location of a mobile device includes at least one server comprising a data structure containing precise positioning subscription options associated with the mobile device, a plurality of client internet of things devices configured to communicate with the at least one server, wherein at least one of the plurality of client internet of things devices is a serving internet of things device configured to provide precise positioning information to the mobile device, and wherein the serving internet of things device is selected from the plurality of client internet of things devices based on the precise positioning subscription options.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine proximate vehicles, for example, vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate, through the use of broadcast or other messages sent by the other vehicles, and to obtain GNSS carrier phase measurement data from the proximate vehicles wherein the shared carrier GNSS phase measurement data may be utilized to update the location(s) of proximate vehicles.

Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station. To enable this, embodiments account for differences in atmospheric effects between the rover station and base station when determining a GNSS position fix for a mobile device (rover station), allowing for a separate tropospheric delay error for a base station to be determined. Embodiments may use additional satellite measurements for which no RTK correction is available, and may further use orbital clock correction for these additional satellite measurements.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine location relative to a roadside unit (RSU) or other nearby point of reference. Vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate to a roadside unit, through the use of broadcast or other messages sent by the vehicles and/or the RSU may share carrier GNSS phase measurement data, wherein the shared GNSS carrier phase measurement data may be utilized to control and coordinate vehicle movements, velocity and/or position by the RSU and/or to determine location of each vehicle relative to the RSU and/or to other vehicles or determine the absolute location of each vehicle. An RSU may coordinate vehicle access to an intersection, manage vehicle speeds and coordinate or control vehicle actions such as slowing, stopping, and changing lanes or sending a vehicle to a particular location.

Abstract: A method of determining a location of a measurement device includes determining, at a server: measurement times of first positioning signal measurements, of first positioning signals from first positioning signal sources and/or a subset of positioning signal sources of second positioning signal sources. The method includes sending at least one measurement command from the server to the measurement device to cause the measurement device to obtain the first positioning signal measurements in accordance with the measurement times and/or obtain second positioning signal measurements of second positioning signals sent from the subset of positioning signal sources. The method includes: receiving, at the server from the measurement device, measurement data corresponding to the first positioning signal measurements and/or the second positioning signal measurements; and determining, at the server, the location of the measurement device based on the measurement data.

Abstract: Techniques for enhanced Global Navigation Satellite Systems (GNSS) position determination can include capturing an image, from a camera, of obstructions near a mobile device. Orientation information regarding the camera can is used to determine where, in the image, the horizon is situated, and which portions of the sky are blocked by the obstructions from the perspective of the mobile device. Information regarding the location of satellites in the sky is obtained, based on an estimated position of the mobile device. Obstructed satellites can then be identified by comparing the location of the satellites with the obstructed portions of the sky. In a GNSS position determination, information received from the obstructed satellites can then be disregarded or de-weighted accordingly. In some embodiments, the information regarding the blocked portions of the sky can be sent to a server and/or shared with other nearby mobile devices.

Abstract: An electronic indictor device (100) for cleaning monitoring can be disposed in a wash chamber of a washer-disinfector to monitor the efficacy of a cleaning cycle. The electronic indicator device (100) includes an environmental sensor (110) configured to generate signals indicative of environmental conditions and a processor (120) configured to determine the efficacy of the figured cleaning cycle based on the signals generated by the environmental sensor (110).

Abstract: The Dual Carrier Field Effect Transistor is characterized by implementing different N-doped and P-doped regions to form channels with narrow cross-sectional area at z=Lz. The placement of the source terminal, the drain terminal and the contact terminal is of a two dimensional structure. This invention overcomes the restriction due to lithographic technology and the effective channel length can be reduced to as short as 5 nm even when presently standard semiconductor technology is used. The supply voltage can be decreased to 0.65V, and each transistor can be designed to have 3 to 12 channels to form Dual Carrier Field Effect Transistor complementary inverters and matrix system-on-a-chip with output current as high as 10 amperes. These devices can also be designed to form complicated, high speed and low power dissipation logic circuits as well as high frequency, low power dissipation microwave circuits and system-on-a-chip.
