Patent number: 11570790Abstract: A method for communicating in a wireless sensor network (WSN) is described. Using control logic, a first wireless transceiver is caused to transmit a wireless packet to a node in a wireless sensor network. The control logic bases its causing on a transmission coinciding with a break in transmission for a second wireless network, such that the transmission from the first wireless transceiver does not coincide with transmissions made on the second wireless network. Time synchronized channel hopping (TSCH) slot frames for wireless packet transmission in the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing TSCH. Wake up sequence transmissions for the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing coordinated sampled listening (CSL).Type: GrantFiled: November 11, 2019Date of Patent: January 31, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ariton E.

Patent number: 11449175Abstract: In some examples, an input device includes a non-linear component, such as a diode. In response to a drive signal, such as a sinusoidal wave, the non-linear passive input device can produce a non-linear output that includes frequency content at the second and other higher harmonics of the fundamental frequency of the drive signal, for example. In some examples, drive electrodes can be driven with a drive signal having one of two fundamental frequencies such that the frequency of the drive signals are applied in an alternating pattern. The electronic device can sense the signal of the stylus to determine the coarse location of the stylus along the sense electrodes and, based on the frequency content of the received signal, a fine location along the axis of the drive electrodes.Type: GrantFiled: March 31, 2020Date of Patent: September 20, 2022Assignee: Apple Inc.Inventors: Srinath Hosur, Aryan Hazeghi, John Stephen Smith
