Abstract

Abstract A power conservation device for a peripheral interface module configured for use in an electronic device includes a sensing means that senses whether the module is in use, and a switching means that connects power from the electronic device to the module when the module is in use, and disconnects power from the electronic device to the module when the module is not in use. The peripheral interface module is designed for use with a peripheral device that is coupled to the module via a peripheral device plug. The peripheral device plug engages a socket provided in the module. The sensing means senses whether the plug engages the socket as an indication of whether the module is actually in use. In response, the switching means disconnects power from the electronic device to the module when the plug does not engage the socket, and connects power from the electronic device to the module when the plug does engage the socket. The power conservation device generally limits power consumption to periods in which the module is in use, thereby improving power efficiency and conserving battery resources in the electronic device.

The peripheral interface module of claim 33, wherein said switching means comprises a switch mounted within said housing, and said sensing means comprises an actuator of said switch, said actuator being engaged by a portion of said socket when said socket is retracted into said housing and disengaged by said portion of said socket when said socket is extended from said housing, said switch including a switching terminal that is opened by said actuator when said portion of said socket engages said actuator, and closed by said actuator when said portion of said socket does not engage said actuator, and wherein said switching means further comprises: a transistor having a first electrode coupled to said electronic device power terminal, a second electrode coupled to said module power terminal, and a control electrode coupled to said switching terminal of said switch, said transistor conducting substantially no current from said first electrode to said second electrode when said switching terminal is open, thereby disconnecting said module power terminal from said electronic device power terminal, and said transistor conducting current from said first electrode to said second electrode when said switching terminal is closed, thereby connecting said module power terminal to said electronic device power terminal.
Claim 43
Dependent Claim 302 words
The peripheral interface module of claim 33, wherein said switching means comprises a switch mounted within said housing, and said sensing means comprises an actuator of said switch, said actuator being engaged by a portion of said socket when said socket is retracted into said housing and disengaged by said portion of said socket when said socket is extended from said housing, said switch including a switching terminal that is opened by said actuator when said portion of said socket engages said actuator, and closed by said actuator when said portion of said socket does not engage said actuator, and wherein said switching means further comprises: a transistor having a first electrode coupled to said electronic device power terminal, a second electrode coupled to said module power terminal, and a control electrode, said transistor conducting current from said first electrode to said second electrode in response to an enable signal received by said control electrode, thereby connecting said module power terminal to said electronic device power terminal, and said transistor conducting substantially no current from said first electrode to said second electrode in response to a nonenable signal received by said control electrode, thereby disconnecting said module power terminal from said electronic device power terminal; and a microprocessor having an input coupled to said switching terminal of said switch and an output coupled to transmit said enable signal and said nonenable signal to said control electrode of said transistor, said microprocessor generating said enable signal at said output when said switching terminal is closed, thereby biasing said transistor to connect said module power terminal to said electronic device power terminal, and said microprocessor generating said nonenable signal at said output when said switching terminal is open, thereby biasing said transistor to disconnect said module power terminal from said electronic device power terminal.
Claim 44
Dependent Claim 189 words
The peripheral interface module of claim 33, wherein said switching means includes a module power contact coupled to said module power terminal and an electronic device power contact coupled to said electronic device power terminal, said module power contact and said electronic device power contact being mounted on said housing, and said sensing means includes a contact pad mounted on said socket and positioned to simultaneously engage said module power contact and said electronic device power contact only when said socket is extended from said housing, said contact pad sensing the simultaneous engagement of said contact pad, said module power contact, and said electronic device power contact, said contact pad connecting said module power terminal to said electronic device power terminal via said module power contact and said electronic device power contact when said contact pad simultaneously engages said module power contact and said electronic device .power contact, and disconnecting said module power terminal from said electronic device power terminal via said module power contact and said electronic device power contact when said contact pad does not simultaneously engage said module power contact and said electronic device power contact.
