Abstract: The teachings relate to a method of distributing to a user a system to provide a remedy for inadequate battery life in a handheld device. The system comprises a modular hybrid-charger assembly operably connected to a device holder. The modular hybrid-charger assembly comprises a rechargeable internal battery connected to a port operable to function as a connection to a portable electronic device, a power management engine embodied in a computer readable medium, and a solar energy source. The device holder comprises a framework operable to receive, hold, and release the portable electronic device; and an alignment mechanism that facilitates a mating of the portable electronic device with the hybrid-charger assembly. The modular hybrid-charger assembly can comprise a form factor that is interchangeable and operable with each of several different device holder form factors.

Abstract: The teachings relate to a power supply for a portable electronic device. The power supply comprises a modular hybrid-charger assembly operably connected to a device holder. The modular hybrid-charger assembly comprises a rechargeable internal battery connected to a port operable to function as a tetherless connection to a portable electronic device, a power management engine embodied in a computer readable medium, and an untethered solar energy source. The device holder comprises a framework operable to receive, hold, and release the portable electronic device; and an alignment mechanism that facilitates a mating of the portable electronic device with the hybrid-charger assembly. The modular hybrid-charger assembly can comprise a form factor that is interchangeable and operable with each of several different device holder form factors.

Abstract: The teachings relate to a power supply that can be used to carry, charge, and power a portable electronic device, as well as be operable by a user while mobile, between or during uses of the portable electronic device. The power supply comprises a modular hybrid-charger assembly operably connected to a device holder. The modular hybrid-charger assembly comprises a rechargeable internal battery connected to a port operable to function as a tetherless connection to a portable electronic device, a power management engine embodied in a computer readable medium, and an untethered solar energy source.

Abstract: A security guard for mounting to a frame of a window opening in a building includes an elongated channel bar having a plurality of mounting pins secured to one end thereof and a key actuated lock visible and operable only from the interior of the building mounted within the confined flanged area of the bar at the opposite end thereof, the mounting pins and the retractable dead bolt of the lock cooperative with adjacent window frame structure to securely but releasably retain the channel bar in position next to the window on the interior side thereof. The spaced pins prohibit the bar from being rotated and an additional lock cover member mounted to the bar substantially coextensive of the lock protects the lock from external tampering. Suitable grill work or the like may be mounted to and supported by the channel bar.

Abstract: An acoustic coupler is provided for extending the listening and signal garing capabilities of an existing cable connected hydrophone system. The acoustic coupler includes a sensor, such as an additional hydrophone, an acoustic projector, and a cable which electrically connects the acoustic projector to the additional hydrophone. A modulator is interconnected in the cable between the projector and the additional hydrophone for modulating signals received by the additional hydrophone on a carrier wave which is within the bandpass of the existing hydrophone. With this arrangement the acoustic projector can be placed in water within listening distance of the existing hydrophone so that signals from the additional hydrophone can be transmitted over the existing hydrophone and its cable system.
