Title: Radio communications systems and methods for jittered beacon transmission
Inventor: HAARTSEN JACOBUS CORNELIS
IPC: H04B7/26
Filed: 1997-08-22
Abstract: PURPOSE: A radio communication system is provided to readily maintain synchronization with one or more private radio communications network base stations without losing synchronization due to repeated radio beacon burst collisions between the base stations CONSTITUTION: Radio beacon transmission between a private radio communications base station and a mobile terminal within the transmission range of the private radio communications base station designed to prevent interference with overlapping uncoordinated private radio communications networks is provided by jittered beacon transmission. The private base station transmits radio beacon bursts at jittered time intervals, which vary pseudo randomly to prevent repeated radio beacon collisions between uncoordinated private radio communications networks with overlapping transmission ranges. The beacon time jittering is performed pseudo randomly in a pattern which is associated with a base station identification value. The mobile terminal derives the base station associated identification value and status information from a received radio beacon and determines if the base station is available for communications with the mobile terminal. The mobile terminal further synchronizes with the jittered base station beacon transmissions based on the pre-determined jitter generation function associated with the base station identification value derived from the received radio beacon.

Abstract: PURPOSE: Provided are skin care compositions containing an N-substituted fatty acid amide and retinol or retinyl ester. CONSTITUTION: Provided is a skin conditioning composition containing: (a) from about 0.001% to about 10% of retinol or a retinyl ester; (b) from about 0.0001 % to about 50% of a N-substituted fatty acid amide of formula 1 which inhibits at least 20% of LRAT or ARAT catalyzed retinol esterification at 100 microM concentration as measured by an in vitro Microsomal Assay; and (c) a cosmetically acceptable vehicle. Wherein R1 is alkyl or alkoxy having from 1 to 10 carbon atoms; R2 =alkyl or alkenyl having from 8 to 25 carbon atoms; R3 =alkyl containing 1 to 5 carbon atoms, or a phosphate ester. The composition prevents and treats dry skin, photodamaged skin, appearance of wrinkles, age spots, aged skin, increases stratum corneum flexibility, lightening skin color, controls sebum excretion and generally increases the quality of skin. The composition may be used to improve skin desquamation and epidermal differentiation. The N-substituted fatty acid amide substantially improves the performance of retinol or a retinyl ester.
