Title: Wheel hub
Inventor: LIPPIS DANIEL J
IPC: F16D65/12
Filed: 2008-09-04
Abstract: The invention is directed to outside diameter piloting apparatus and method for concentrically aligning a disc rotor to a wheel hub. The pitch circle diameter of the annular piloting features is greater than the pitch circle diameter of the rotor mounting fasteners and the wheel studs of the hub. The outside diameter piloting feature allows a hub section profile which is smooth and continuous between the inboard side of the wheel hub up to the mounting fastener apertures.

Patent CA-2640285-A1 (CA)
Title: Livestock water bowl
Inventor: KENNY ANDREW
IPC: A01K7/06
Filed: 2007-01-25
Abstract: A water vessel for providing water to livestock animals in tie stalls is described. The vessel features a sensor for providing water in response to a sensed presence of a livestock animal's head within the vessel. As water is provided to the vessel, the livestock animal is compelled to lift their head and thereby withdrawing their head from the region sensed by the sensor. In this way, the depth of water in the vessel is maintained within a predetermined range. The vessel also comprises a rim that is disposed sufficiently above the predetermined range of water levels that the livestock animal is compelled to lift their head in a substantially vertical fashion in order to withdraw their head from the vessel. This serves to reduce the spillage of water from the vessel.

Abstract: Orthogonal Code Division Multiplexing (OCDM) transceiver system with Complementary Code Keying (CCK) and method for baseband OCDM-CCK  encoding and decoding are provided. The OCDM-CCK method comprises a serial-to-parallel data converter converting a stream of M*n-bit serial data to n-bit parallel data in 'M' parallel baseband paths, and encoding each n-bit data segment with a distinct complementary code using CCK modulation for spreading. The CCK encoded baseband signals are all summed and transmitted simultaneously on the same carrier frequency and spread spectral bandwidth.  The OCDM-CCK method of encoding and transmission of information, results in enhanced datarates of 33 Mbps, 88 Mbps, 176 Mbps and higher multiples of 5.5 Mbps with backward compatibility for IEEE 802.11b WLAN (Wireless Local Area Network), and wireless communication networks supporting real time Direct Sequence Spread Spectrum (DSSS).

Patent CA-2652221-A1 (CA)
Inventor: FRIES ROBERT M
IPC: G06F12/16
Filed: 2007-03-15
Abstract: Data in backup systems can be effectively protected against viruses, even if definitions for certain viruses are found after infected data have been backed up to a backup server. In one implementation, a combined filter that includes antivirus and replica filtering components can identify and process I/O system calls (e.g., including writes to files). If a virus is present, the antivirus component of the combined filter can mark the file and/or file write (and cleanse the file/file write), and pass that information to the replica component. If the file write is associated with a file to be backed up, the replica component can then pass along the antivirus filter's indications with a copy of the file write. The backup server can also identify that previous versions of the file stored at the backup server may have been infected, and can thus perform any appropriate actions.
Patent CA-2652880-A1 (CA)
Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N19/89
Filed: 1994-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.
