Abstract
A power-saving computer mouse having installed therein a switching transistor and a proximity sensor switch formed of a capacitive proximity sensor and a charge induction plate for controlling said switching transistor to switch on the power supply circuit when the user holds the computer mouse with a hand, or to switch off the power supply circuit when the user moves the hand away from the computer mouse.
Claims4
A power-saving computer mouse comprising:
- a housing, a microprocessor, a wireless transmitter, a button and roller/optical signal receiving and processing unit, a transmitting antenna, and a battery set,
- a switching transistor defining a conduction path switchably connecting said button and roller/optical signal receiving and processing unit to system ground, and
- a proximity sensor switch for controlling said switching transistor to switch on/off said battery set by proximity-sensing an approach of a user's hand, said proximity sensor switch comprising a capacitive proximity sensor and a charge induction plate mounted inside said housing, said capacitive proximity sensor providing a high potential output to wake up said microprocessor and to trigger said switching transistor in switching on said battery set when an operator holds said housing with a hand, said capacitive proximity sensor providing a low potential output to have said microprocessor enter sleep mode and said switching transistor switch off said battery set when the operator moves the hand away from said housing.
A power-saving computer mouse comprising:
- a microprocessor, a button and roller/optical signal receiving and processing unit, and a cable connectable to a computer to obtain power supply therefrom,
- a switching transistor defining a conduction path switchably connecting said button and roller/optical signal receiving and processing unit to system ground, and
- a proximity sensor switch for controlling said switching transistor to switch on/off button and roller/optical signal receiving and processing unit by means of proximity-sensing an approaching of a user's hand, said proximity sensor switch comprising a capacitive proximity sensor and a charge induction plate mounted inside said housing, said capacitive proximity sensor providing a high potential output to wake up said microprocessor and to trigger said switching transistor in switching on said button and roller/optical signal receiving and processing unit when an operator holds said housing with a hand, said capacitive proximity sensor providing a low potential output to have said microprocessor enter sleep mode and said switching transistor switch off said button and roller/optical signal receiving and processing unit when the operator moves the hand away from said housing.
