Abstract: The invention is a device for multi-band, multi-channel, wireless communications that automatically provides signal amplification when and where necessary, and that automatically avoids harmful interference to base stations and other parts of the communications infrastructure. The invention is a unique combination of an adjustable gain, bidirectional amplifier, a GPS receiver, a processor, and one or more removable, non-volatile, updatable memory devices. Alternatively, the memory can be an internal device accessible via an electronic port such as a USB. In either case, the memory stores comprehensive information that determines if, and how much, amplification is necessary at a particular location sensed by the GPS receiver. The device also includes a dedicated apparatus that permits a deactivation by remote control in the event of a malfunction.

Abstract: The invention is a device for multiband, multi-channel, wireless communications that automatically provides signal amplification when necessary, and that automatically avoids harmful interference to base stations and other parts of the communications infrastructure. The device is especially suitable for, but not limited to, cellular and PCS bands and channels. The invention is a unique combination of a bidirectional amplifier, a GPS receiver, a processor, and a removable, updatable memory. The memory stores comprehensive information that determines if amplification is necessary at a particular location sensed by the GPS receiver. Because the memory is removable and updatable, it therefore provides protection against piracy and unauthorized and improper use.

Abstract: An insertable flashlight adapter device for use in an ordinary flashlight having a lamp includes a disc-like shaped housing unit. Electronic circuitry is disposed within the housing unit for selectively operating the flashlight in at least three different modes. The electronic circuitry has a voltage comparator for determining which one of the at least three different modes the flashlight is being operated. The electronic circuitry also has logic and control means for selectively interrupting current to the flashlight lamp so as to cause the at least three different modes of operation. The logic and control means includes a first timer for monitoring a first time interval between mode changes in the voltage comparator and a second timer for monitoring a second time interval between a power-ON and power-OFF state of the flashlight lamp.
