Abstract
A wireless audio system, including an audio and radio frequency module, that is prevented from being accidentally turned off by using an electronic gate responsive to a gate signal for coupling electrical power from a source to the module which bypasses the normal mechanical power switch. Means are provided for generating the gate signal in response to operation by the user so that the user cannot accidentally turn off the system by moving the power switch to its off position.
Claims15
In a wireless audio system including an audio and radio frequency module, improved apparatus for preventing a user from accidentally turning off said system comprising in combination:
- a source of electrical power for said system;
- a power switch coupled to said source, said power switch having a first position for normally preventing electrical power from being coupled to said module and a second position for enabling electrical power to be coupled to said module;
- an electronic gate responsive to a gate signal for coupling electrical power from said source to said module;
- and
- means for generating said gate signal in response to operation by said user, whereby electrical power is delivered to said module when said power switch is in said first position so that said user cannot accidentally turn off said system by moving said power switch to said first position.
In a wireless audio system including an audio and radio frequency module, a source of electrical power for said system and a power switch coupled to said source, said power switch having a first position for normally preventing electrical power from being coupled to said module and a second position for enabling electrical power to be coupled to said module, an improved method for preventing a user from accidentally turning off said system comprising in combination the steps of:
- coupling electrical power from said source to said module through an electronic gate in response to a gate signal;
- and
- generating said gate signal in response to operation by said user, whereby electrical power is delivered to said module when said power switch is in said first position so that said user cannot accidentally turn off said system by moving said power switch to said first position.
