Wireless identification device, RFID device with push-on/push off switch, and method of manufacturing wireless identification device

A radio frequency identification device comprising:

• a housing;
• an integrated circuit in the housing including a receiver having an enable input, the receiver being selectively enabled in response to application of a signal of a predetermined voltage value on the enable input, the receiver being configured to receive an interrogation signal when enabled, the integrated circuit further including a transmitter configured to provide a signal to identify the device in response to an interrogation signal;
• and
• a switch supported by the housing and configured to cause the receiver to be enabled in response to being pushed while the receiver is disabled and to cause the receiver to be disabled in response to being pushed while the receiver is enabled, the switch including a first conductor formed of printed thick film and having a first end coupled to the predetermined voltage value and having a second end, a second conductor formed of printed thick film and having a first end coupled to the enable input and having a second end spaced apart from the second end of the first conductor, an insulating ring having a periphery circumscribing the second end of the first conductor and the second end of the second conductor, a diaphragm having a periphery corresponding to the periphery of the insulating ring, and having a conductive face facing the second end of the first conductor and the second end of the second conductor, the conductive face of the diaphragm being spaced apart from the first and second conductors by the insulating ring.

A radio frequency identification device comprising:

• a housing including a substrate, and encapsulant over the substrate;
• an integrated circuit in the housing including a receiver having an enable input, the receiver being selectively enabled in response to application of a signal of a predetermined voltage value on the enable input, the receiver being configured to receive an interrogation signal when enabled, the integrated circuit further including a transmitter configured to provide a signal to identify the device in response to an interrogation signal;
• and
• a switch supported by the housing and configured to cause the receiver to be enabled in response to being pushed while the receiver is disabled and to cause the receiver to be disabled in response to being pushed while the receiver is enabled.

A method of manufacturing a wireless identification device, the method comprising:

• configuring circuitry to provide a signal to identify the device in response to an interrogation signal;
• coupling the circuitry to a push on and push off switch supported by the housing and controlling whether the circuitry provides the signal to identify the device;
• and
• encasing the circuitry in a housing such that the switch is actuable from outside the housing by touching a portion of the housing.

A method of manufacturing a wireless identification device, the method comprising:

• supporting a battery on a film substrate, the battery having first and second terminals of opposite polarity;
• supporting circuitry on the substrate to provide a signal to identify the device in response to an interrogation signal when enabled;
• supporting a latch on the substrate, and coupling the latch to the circuitry such that the latch toggles the circuitry between being enabled and disabled;
• forming a push on and push off switch on the substrate and coupling the switch to the latch;
• coupling the circuitry to the battery to connect the circuitry to the battery;
• and
• flowing an encapsulant over the circuitry, latch, switch, and battery to define a housing including the encapsulant and the substrate.

A radio frequency identification device comprising:

• a housing including a polyester film substrate;
• an integrated circuit in the housing including a receiver having an enable input, the receiver being selectively enabled in response to application of a signal of a predetermined voltage value on the enable input, the receiver being configured to receive an interrogation signal when enabled, the integrated circuit further including a modulated backscatter transmitter configured to provide a signal to identify the device in response to an interrogation signal;
• and
• a switch supported by the housing and configured to cause the receiver to be enabled in response to being pushed while the receiver is disabled and to cause the receiver to be disabled in response to being pushed while the receiver is enabled, the switch including a first conductor formed of printed thick film and having a first end coupled to the predetermined voltage value and having a second end, a second conductor formed of printed thick film and having a first end coupled to the enable input and having a second end spaced apart from the second end of the first conductor, an insulating ring having a periphery circumscribing the second end of the first conductor and the second end of the second conductor, a diaphragm having a periphery corresponding to the periphery of the insulating ring, and having a conductive face facing the second end of the first conductor and the second end of the second conductor, the conductive face of the diaphragm being spaced apart from the first and second conductors by the insulating ring.
