Latest Patents

Wei-Chi Lai's latest patents include a communication device and collision detection method. This device features a radio transceiver and a collision detection device. The radio transceiver is designed to receive a wireless signal that includes an acknowledgment packet from a wireless communication channel. The acknowledgment packet contains information corresponding to multiple transmitted packets. The collision detection device, connected to the radio transceiver, determines if a collision has occurred in the wireless communication channel based on the acknowledgment information. It generates a detection result indicating whether a collision has occurred when the acknowledgment information is concentrated in a specific section of the acknowledgment packet.

Another notable patent is a communication device and method for dynamically adjusting packet detection thresholds. This device includes a packet detection circuit, a decoding circuit, and a threshold decision circuit. The packet detection circuit performs detection based on at least one threshold to identify if a packet is present in a received signal. The decoding circuit decodes the packet when detected and checks if it is a predetermined packet. The threshold decision circuit calculates the number of predetermined packets received over a time period and adjusts the detection threshold accordingly.
