Abstract: A lock for an access door having an electrically powered electronic smart lock control and a keyless mechanical lock control, and a single locking bolt element. The single locking bolt element is made movably operable, to permit opening of the access door, with either of an electronic code entry via the electrically powered electronic smart lock control or a mechanical code entry via the keyless mechanical lock control. The mechanical lock control, with mechanical code entry, thereby provides a fail-safe back up for keyless entry through the access door in the event of electrical failure on the electronic smart lock.

Abstract: A smart lock system and method having a smart lock element, a data entry interface element; a mechanically operated power generator such as a dynamo as the sole power source; and an electronic control element. A separate controller is in communication with the smart lock element, only when the dynamo provides power to the smart lock. The controller element constantly receives and store updated key code information from a remote location source. With the providing of the operating energy to the smart lock the electronic control element receives and stores updated key code information from the controller, if any, prior to any unlocking activation of the locking mechanism. The electronic control element compares stored key code information with entered key codes and the locking mechanism is unlocked thereafter with entry of a valid key code corresponding to a key code stored in the electronic control element.

Abstract: A battery powered smart lock comprising a locking mechanism with an interface element for entry of an unlocking code for controlling the locking mechanism, the interface element being in an electrical circuit with the battery which provides power for the operation of the interface element and unlatching operation of the locking mechanism. The smart lock further comprises a mechanically operated dynamo in an electrical circuit with the interface element wherein the dynamo is externally mechanically operated to provide sufficient electrical energy to power operation of the interface element and unlatching operation of the locking mechanism, in the event that the battery becomes incapable of providing a requisite power operation to unlatch the locking mechanism.

Abstract: A secure key storage device integrable with an electronic lock having a mechanical key override activation and a mechanical lock. The storage device contains and provides a key which can open the electronic lock on a mechanical override basis via the mechanical lock and is comprised of a locking key caddy compartment which contains the key, and which is provided with a mechanical lock opening member to effect opening thereof. The secure key storage device has a mounting element with a structure configured to be fitted with and securely supported by the mechanical lock of an existing electronic lock on the door and wherein the locking key caddy compartment element is integrated with the mounting element either by fastening elements or as a one piece structure. Alternatively, or in addition a spare battery compartment element is provided with a spare charged battery.

Abstract: A transportable desktop computer convertible to a notebook computer with minimal footprint. The computer has a screen element, with contained computer operational elements, and a support stand. The screen element is releasably hingedly attached to a keyboard element having two members with one member including the operational keyboard and pointing device the other being foldable under the keyboard for minimal keyboard footprint.

Abstract: A split air conditioning apparatus is readily installed at a window opening by accessible actuators. The apparatus is affirmatively prevented from falling from the window opening, both during and after installation.

Abstract: A disposable razor comprising a blade holder, a blade in the blade holder, a handle connected to the blade holder and a blade cover. In order to indicate the number of times the blade has been used, tabs are integrally formed on the handle, blade holder or the blade cover and bendable about a pivot line from a first position indicating non-use to a second position indicating one use and indicia associated with each tab.

Abstract: A system for remotely controlling call forwarding for a given telephone line, comprises detecting the receipt of a remotely transmitted identification code to the given telephone line, storing a desired call forwarding telephone number remotely transmitted after the identification code, and seizing the given telephone line and applying a call forwarding initiate code thereto followed by the stored telephone number. The receipt of a remotely initiated signal is detected at the given telephone line and the given line is seized upon a favorable detection and a call forwarding terminate code is applied.
