Publication number: 20240112429Abstract: A method of providing an interactive personal mobility system, performed by one or more processors, comprises determining an initial pose by visual-inertial odometry performed on images and inertial measurement unit (IMU) data generated by a wearable augmented reality device. Sensor data transmitted from a personal mobility system is received, and sensor fusion is performed on the data received from the personal mobility system to provide an updated pose. Augmented reality effects are displayed on the wearable augmented reality device based on the updated pose.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Edmund Graves Brown, Benjamin Lucas, Jonathan M.

Patent number: 8897829Abstract: One aspect provides a method of controlling transmit power in a wireless device, wherein a desired transmit power is determined as a result of detection of a receive signal parameter. The method comprises detecting a desired maximum transmit power and generating a sequence of attenuation factors. The sequence is generated by monotonically increasing a variable at a controlled rate between a starting value and the maximum transmit power. The method further comprises using each attenuation factor in turn to: (a) reduce the measured value of the received signal power; and (b) reduce a determined desired value of the transmit power, where the transmit power is continually reduced as the variable is increased.Type: GrantFiled: April 17, 2013Date of Patent: November 25, 2014Assignee: NVIDIA CorporationInventors: Robert Buckley, Jonathan Lucas, Edward Charles John Andrews, Steve Allpress

Publication number: 20070257970Abstract: The present invention provides a droplet generator (10) of the velocity modulation type, the generator (10) being configured so that substantially all the modulation energy generated by piezo-electric crystals (60) is transformed into vibration of the nozzle (34). The generator preferably also includes an internal closure mechanism (70) which blocks off the nozzle (34) when the generator is not in operation, but which is de-coupled from the modulation process when the generator is operating.Type: ApplicationFiled: September 14, 2005Publication date: November 8, 2007Inventors: Jonathan Morgan, Jonathan Lucas

Patent number: 7257150Abstract: An input signal is mixed with a scrambling code and with an OVSF code, and then accumulated over a period of time equal to one symbol of the pilot channel before being reset. The resultant complex signals are mixed with the conjugate of complex signals provided by a pilot pattern generator, with the result being fed to a delay line (22). A multiplier multiplies the complex value at a location P(n) in the delay line (22) by the conjugate of a complex value at another location P(n+k), and provides the resulting complex number (which is a complex vector whose phase is a coherent measurement of the phase rotation occurring between the symbols corresponding to the two locations) at an output (27). The real part of the complex signal provided at the output (27) is provided to a first combiner (30), and the imaginary part is provided to a second combiner (31). These combiners (30, 31) also receive corresponding signals from all of the other fingers (not shown) of the rake receiver.Type: GrantFiled: November 20, 2001Date of Patent: August 14, 2007Inventors: Diego Giancola, Andrew Thurston, Jonathan Lucas
