Title: Robust frequency management and acquisition in a wireless local area network that uses frequency-hopping radios
Inventor: FLEEK ARTHUR E
IPC: H04B1/7156
Filed: 1995-07-07
Granted: 2001-12-11
Abstract: A method for use in a single cell of a wireless communication system of the type having a leader station that coordinates communication among a plurality of remote stations that are in the cell. The method applies to systems that use slow frequency-hopping radios and a Carrier Sense Multiple Access (CSMA) type protocol. In this context, the method allows a remote station to initially acquire the frequency-hopping pattern and time base of the leader station and to maintain frequency synchronization in the face of control information loss due to radio transmission effects (e.g., interference, noise or multipath fading). In the acquisition phase, the remote station actively generates probe messages that are sent to the leader station so as to rapidly achieve frequency synchronization with the leader station.

Abstract: A nested digital phase lock loop (DPLL) circuit (400) provides center bit sampling for incoming recovered data (406). Included in the nested DPLL circuit (400) are a narrow bandwidth DPLL (402) and a wide bandwidth DPLL (404) which generate first (410) and second (428) recovered clock signals respectively. Initially the first recovered clock signal (410) is used to clock in the recovered data (406) until the narrowband DPLL (402) is stabilized. Once the narrowband DPLL (402) is stabilized, the second recovered clock signal (428) generated from the wideband DPLL (404) is switched in by a multiplexer (424). If for any reason the center bit sampled data becomes corrupted, a RESET occurs in the wideband loop (404) to zero out the phase shift of the second recovered clock signal (428) to match that of the narrow loop. Thus, when a RESET occurs, the wideband loop is tracking at exactly the same clock rate as the narrowband loop.

Abstract: A vibration damping device for mounting between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. An inner metal cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with the outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to the other portion of the vehicle. An outer housing surrounds a portion of the inner housing and forms a fluid transfer duct between fluid chambers formed on opposite sides of the piston within the piston chamber. A plurality of spaced metal electrode bands are mounted on an inner surface of the outer housing and are electrically isolated therefrom and communicate with the fluid transfer duct for applying voltages across the duct to affect the viscosity of an electrorheological (ER) fluid flowing therethrough to increase the damping force of the device. Certain of the electrode bands may be formed with a plurality of circumferentially spaced, longitudinally extending splines and intervening grooves, which grooves align with splines and grooves formed in a dielectric insulating sleeve mounted adjacent the fluid transfer duct.

Granted: 2004-08-31
Abstract: A timing device which is associated with a light level sensor and which is arranged to provide a time-out signal to a relay after a predetermined time has elapsed following detection of a low light condition and initial energisation of the relay. The device provides for synchronisation of an initiation time T1 and, hence, a time-out signal generating time T2 with respect to a periodically occurring event time T3 (for example, sunset time) in order that the desired time of generating the time-out signal might be re-established following interruption of power to the device. Should loss of power occur, the last entered event time T3 is employed to synchronise the initiation time T1 and, hence, the signal generating time T2, when detection of a predetermined light level next occurs following re-establishment of power to the device.
