Patent CA-2547372-A1 (CA)
Inventor: PLETT CALVIN
IPC: H04B1/40
Filed: 2006-05-18
Abstract: A low power (optionally, self-powered) integrated transceiver using on-chip antennas is provided. The transmitter and receiver utilize phase-locked loops (PLLs) which initially, in a closed-loop state, pre-tune (i.e. phase-lock) voltage controlled oscillators (VCOs) before opening the loops to allow them to transmit and receive data. The TX, in the opened-loop state, disables the loop components while (FM) modulating the VCO. The RX, in the opened-loop state, injection-locks the VCO with the incoming (FM) modulated signal while the remaining loop components serve to demodulate the signal. For both the TX and RX an integrated antenna is used and, advantageously, the TX comprises a dual purpose inductor which functions as both an inductor in the voltage-controlled oscillator and the integrated antenna.

Abstract: A method and apparatus for molding a block or sheet of ice that is resistant to breakage and can be readily attached to an external object such as a ski, sled, or other device for the purpose of sliding said objects down or along non-snowy or non-icy terrain. The ice molding apparatus consists of three, typically plastic, parts: a container, a lid, and a grate. The grate is suspended from the container edges down into the container and below the lid, with a portion of the grate extending outside of the container. The lid is mounted on the grate, with the container, grate, and lid all forming a seal to prevent water from easily spilling from the mold apparatus during the ice making and freezing process.  The ice that is formed encapsulates the grid that provides structural reinforcement to the ice block and makes it more resistant to breakage than comparably sized ice blocks when impacted by external physical forces. Additionally, a portion of the grate extends outside of the mold (container and lid) and contains a snap latch or other mechanism of similar purpose for attachment to a mating feature on a sled, ski, or other device.

IPC: H04L12/56
Filed: 2005-09-28
Abstract: In a communication system in which a roaming node seeking network access among different networks which are implemented with different network interface layer protocols, handoff schemes are instituted whereby the node may freely move from one network to another with reduced levels of interruptions with respect to the network access. Prior to and at the onset of a handoff, the node receives an indication for the handoff. The indication may be embodied in various forms such as a signal message indicating a change of the SID (System Identification), NID (Network Identification), or PZID (Packet Zone Identification). Alternatively, the indication can be in the form of information straightforwardly included in a data packet sent to the roaming node prior to the handoff. As another alternative, the indication can be implemented as distinguishable message patterns sent to the node in which different message patterns can be sent by different networks supporting different network interface layer protocols.
