Patent CA-2316316-A1 (CA)
Title: Cylinder head structure of internal combustion engine
Inventor: FUKUZAWA SUMIKO
IPC: F01L3/06
Filed: 2000-08-18
Abstract: An intake port and an exhaust port are formed without changing a passage sectional area or its shape a little and without increasing an entire height of an engine. A seat machining part of a valve guide fixing seat of the intake port and the exhaust port are arranged at the cylinder head and are bent in any one of the right side direction or the left side direction as seen from the center of the valve. With such an arrangement, a minimum thickness for the seat machining can be assured, the intake port and the exhaust port do not change the passage sectional area or the sectional shape a little and so it is not necessary to increase the entire height of the engine.

Title: Method and radio communication system for controlling power between a base station and a subscriber station
Inventor: TRAYNARD JEAN-MICHEL
IPC: H04B7/005
Filed: 1999-10-08
Abstract: According to the invention, transmissions of the second radio station are received in the first radio station in which the operating instruction for transmission power of the second radio station is determined. The operating instruction is transmitted during a following transmission of the first radio station to the second radio station, whereupon the latter takes into account the operating instruction for power regulation during one of its following transmissions. Contrary to prior art, no time invariable or fixed step size is used. An operating instruction is used instead which is related to a variable step size in transmission power regulation. The variable step size is subscriber-dependent and time-dependent regulated by the radio stations.

Patent CA-2365380-A1 (CA)
Inventor: LIMBACH DOUGLAS C
IPC: H04M1/2757
Filed: 2000-10-05
Abstract: A telephone speed-dialer for use with a personal digital assistant (PDA) or other mobile device has an infrared transceiver for communication therewith.  The dialer unit is connected to a land-based phone line, and remains next to a phone. When a user desires to make a phone call to a number on his or her PDA's address book, the user selects the phone number in the address book and sends the number via infrared link (i.e. "beams" it) to the dialer. After the dialer receives the number from the PDA, the dialer senses when the user picks up the receiver of the adjacent phone, and automatically dials the phone number with proper area code and any predialing digits. Preferably, the dialer emulates another PDA receiving an electronic business card from the user's PDA, so that no special software need be installed on the user's PDA other than the existing operating system. To conserve battery power when not in use, the dialer remains in a "sleep mode" until it senses infrared activity. In an alternative embodiment, the dialer communicates with the PDA with a short range radio frequency link, such as that specified in the emerging Bluetooth Standard, instead of with the infrared link.
