Apparatus and method for detection of communication signal loss
First Claim
1. A system for notifying a user of a loss of wireless communication, the system comprising:
- a host device;
at least one peripheral device connected to the host device by a wireless connection, the at least one peripheral device being capable of sending a first signal to the host device, and the host device being capable of sending a second signal to the at least one peripheral device in response to, and verifying receipt by the host device of, the first signal sent by the at least one peripheral device;
wherein the at least one peripheral device is also capable (a) of recognizing that the second signal from the host device has not been received after the sending of the first signal and (b) of then resending the first signal a preselected number of times so long as no second signal is received after each resending of the first signal; and
an alarm responsive to a determination that the second signal has not been received by the at least one peripheral device after the resending of the first signal the predetermined number of times, the alarm notifying the user of the loss of wireless connection between the host device and the at least one peripheral device;
wherein the alarm is configured as part of said at least one peripheral device.

Abstract
A system and method for notifying a user of a loss of wireless communication between a host device and at least one peripheral device is described. The system comprises a host device, at least one peripheral device, means for detecting a loss of wireless connection between the host device and the at least one peripheral device and an alarm notifying the user of the loss of wireless connection between the host device and the at least one peripheral device. A method for notifying a user of a loss of wireless communication between a host device and at least one peripheral device is described, the method comprising detecting a loss of wireless communication between a host device and at least one peripheral device, signaling software controlling a transceiver that the loss of communication has been detected and transmitting a message to alert the user of the loss of wireless communication.

14. A computer based method for wireless communication between a host computer and a first peripheral device, said host computer including a receiver for receiving data in the form of signals from said first peripheral device and said first peripheral device including a receiver for receiving data in the form of signals from said host computer, the method comprising:
-
sending a first signal from the first peripheral device to the host computer, wherein the host computer recognizes the first peripheral as the source of said first signal;
sending a second signal from the host computer to the first peripheral device confirming the receipt of the first signal by the host computer within a preselected time period following transmission thereof;
wherein when said first peripheral device recognizes the second signal from the host computer confirming receipt of the first signal by the host, the first peripheral device sends a third signal to the host computer and awaits confirmation thereof, and wherein when the first peripheral device fails to receive the second signal from the host computer, the first peripheral device retransmits the first signal a preselected number of times; and
initiating an alarm signal notifying a user that the communication between the host computer and first peripheral has been lost after the first peripheral has sent the first signal a preselected number of times with no confirmation thereof. - View Dependent Claims (15, 16, 17)

18. A method for wireless communication between a host device and a first peripheral device, said host device including a receiver for receiving in the form of signals from said first peripheral device and said first peripheral device including a receiver for receiving data in the form of signals from said host device, the method comprising:
-
sending, a first signal from the first peripheral device to the host device, wherein the host device recognizes the first peripheral as the source of said first signal;
sending a second signal from the host device to the first peripheral device confirming the receipt of the first signal by the host device within a preselected time period following transmission thereof wherein when said first peripheral device recognizes the second signal from the host device confirming receipt of the first signal by the host device, the first peripheral device sends a third signal to the host device and awaits confirmation thereof, and wherein when the first peripheral device fails to receive the second signal from the host device, the first peripheral device retransmits the first signal a preselected number of times and initiating an alarm signal notifying a user that the communication between the host device and first peripheral has been lost after the first peripheral has sent the first signal a preselected number of times with no confirmation thereof. - View Dependent Claims (19, 20, 21)

22. A system for notifying a user of a loss of wireless communication, the system comprising:
-
a host device;
at least one peripheral device connected to the host device by a wireless connection, the at least one peripheral device being capable of sending a first signal to the host device, and the host device being capable of sending a second signal to the at least one peripheral device in response to, and verifying receipt by the host device of, the first signal sent by the at least one peripheral device;
an alarm responsive to a determination that the second signal has not been received by the at least one peripheral device, the alarm notifying the user of the loss of wireless connection between the host device and the at least one peripheral device;
wherein the alarm is configured as part of said at least one peripheral device; and
wherein the alarm is audible and comprises a series of beeps increasing in volume over time until the alarm is shut off by the user.
