Patent CA-2304355-A1 (CA)
Title: Unified alerting method and apparatus
Inventor: CLOUTIER JOCELYN
IPC: H04W88/18
Filed: 2000-04-06
Abstract: This invention provides for a unified alerting system that alerts the subscriber via one or more devices. The unified alerting system receives alert events from services subscribed to by the subscriber, filters the alert events and alerts the subscriber via one or more devices identified in a subscriber profile. The alert event is filtered by if-then-else statements that contain conditions and actions. Conditions have Boolean values and the actions set various control variables or may be further if-then-else statements. In this way, the subscriber may specify complex conditions that process each alert event to determine whether the subscriber should be alerted via one of the available devices. The subscriber profile specifies possible devices through which the subscriber may be alerted via a schedule corresponding to each of the devices. The profile also includes a priority level for each of the devices when multiple devices are available. The unified alerting device may also perform various conversions such as voice-to-text and text-to-voice so that messages may be sent in an alert regardless of the capabilities of the devices used.

Title: Pet toy product with integral treats receiving receptacles
Inventor: JOHNSON BRENT P
IPC: A01K29/00
Filed: 1998-11-11
Abstract: A pet toy product for holding one or more animal treats has a body member having an outer surface with one or more recesses for removably holding one or more animal treats. The recesses may be of varying depth so that the treats in the deeper recesses are more difficult for the animal to extract than are the treats in the shallower recesses. The recesses may be circular, triangular, irregular, in the form of a groove or any other suitable configuration. The outer surface of the toy may be raised to accommodate the recesses or the recesses may extend into the surface. The pet toy may have recesses forming openings which extend through the side wall of the pet toy product for receiving treats. With the structure recited, the pet owner can replenish the treats as often as necessary to maintain the pet's interest in the toy. Different treats can be provided with different nutritional values and tastes. Because some treats will be more difficult for the animal to remove than others, the animal can be kept occupied for several hours before; the treats need to be replaced again. The treats may be held in the recesses by friction, adhesive or adhesion.

Patent CA-2313525-A1 (CA)
Title: Process and apparatus for converting an mpeg-2 bitstream into an smpte-259 compatible bitstream
Inventor: BHATT BHAVESH BHALCHANDRA
IPC: H04N7/26
Filed: 1998-12-19
Abstract: A process and apparatus for converting an MPEG-2 bistream into an SMPTE-259 compatible bitstream are characterized by a frame rate converter which is selectively enabled to drop every 1001st frame of the incoming MPEG-2 bitstream depending on the input bitstream frame rate. If the input bitstream frame rate is other than 29.97 or 59.94 Hz, a frame dropper is enabled to discard every 1001st frame. The present converter can convert many different types of input bitstreams, such as all I types, IPIP types, or complex GOP types containing I, P, and B frames. The enabled frame dropper will drop either the I or P frame if it occurs as the 1001st frame, but if the 1001st frame is of the B frame type, the pixel information of the B frame is dropped. This produces a minimum in loss of information during the conversion. The format converter allows existing SMPTE-259 routing equipment to route and utilize MPEG-2 bitstreams, such as HDTV applications.
