Wireless data module with two separate transmitter control outputs
| Details |
Inventors: Bolan, Michael L.; Dias, Donald R.; Payne, II, William Lee;
Assignee: Dallas Semiconductor Corp. (Dallas, TX)
Primary Examiner: Bocure; Tesfaldet
Assistant Examiner:
Attorney, Agent or Firm:
A wireless-accessible module which provides first and second wireless-transmitter control signals, such that the first transmitter control signal can be activated automatically, in response to incoming wireless signals, but the second transmitter control signal can only be activated by manual input or direct command. Preferably the two control signal outputs are used to select the power level of transmission on a single predetermined frequency; but alternatively these outputs may be used to control two different RF transmitters and/or two different antennas. |

DETAILED DESCRIPTION What is claimed is: 1.
A wireless-accessible module, comprising: wireless receiver circuitry to receive a wireless query; a first manual input to receive a manual start signal; control circuitry electrically coupled to each of said wireless receiver circuitry and said first manual input, said control circuitry responsive to said wireless query and said manual start signal; a first transmitter control output generator electrically coupled to said control circuitry, said control circuitry for activating said first transmitter control output generator in response to said wireless query; a second transmitter control output generator electrically coupled to said control circuitry, said control circuitry further for activating said second transmitter control output generator in response to said manual start signal; and a touch interface adapted for one-wire serial data transmission, said touch interface electrically coupled to said control circuitry, said control circuitry further for deactivating each of said first and second transmitter control output generators in response to access of said touch interface wherein, if said touch interface has not been accessed and said wireless receiver circuitry receives said wireless query, said control circuitry activates said first transmitter control output generator to transmit data as keyed signals of an output frequency with a keying frequency less than said output frequency, and thereafter goes silent, and thereafter goes active again, in a pattern having durations which are varied quasi-randomly, and further wherein if said touch interface has been accessed, said control circuitry deactivates each of said first and second transmitter control output generators and transmits data through said much interface.
2.
The wireless-accessible module of claim 1, wherein said wireless-accessible module further comprises a first RF transmitter electrically coupled to said first transmitter control output generator to transmit outputs generated by said first transmitter control output generator and a second RF transmitter electrically coupled to said second transmitter control output generator to transmit outputs generated by said second transmitter control output generator
