Patent CA-2661204-A1 (CA)
Inventor: GOROKHOV ALEXEI
IPC: H04L1/00
Filed: 2007-09-11
Abstract: Systems and methodologies are described that provide techniques for managing persistent resource assignments in a wireless communication system. An access point can generate a bitmap by mapping access terminals having persistent assignments for traffic channels to a series of bitmap bits that provide keep-alive indications for the access terminals. The bitmap can then be provided as a common keep-alive message in a broadcast or multicast transmission to the access terminals. The keep-alive message can further include CRC bits for error prevention. An access terminal, upon receiving the keep-alive message, can then determine whether a bitmap bit in the keep-alive message corresponding to the access terminal conveys a keep-alive indication for the terminal and utilize its persistently assigned traffic channels accordingly.

Patent CA-2672113-A1 (CA)
Title: Ultrasonic airspeed indicator for aircraft
Inventor: ERDMANN ERICH
IPC: G01P5/24
Filed: 2009-07-16
Abstract: For an aircraft to be operated safely its speed in reference to the surrounding air must be measured precisely in order to avoid such disasters as stalling due to too low an airspeed or structural damage caused by too high an airspeed. At the present time in general most airspeed indicators used in aircraft measure the airspeed indirectly by means of a small bend piece of pipe fastened underneath the wing and connected by a length of tubing to an air pressure gauge located inside the cockpit. This device only registers the air pressure and not the actual airspeed, but instead of giving readouts of the air pressure in pounds per square inch, the pressure gage instrument is marked in corresponding miles or kilometers per hour, which under normal conditions works well but can give under certain conditions false readings. The Ultrasonic Airspeed Indicator contrary to this measures the true speed of the aircraft in reference to the air by means of the effect as it alters the measured speed of sound. This sound is being generated and transmitted by a speaker plus microphone type of instrument with its supporting electronic circuitry.
