Abstract: A method and system for the detection of an object in a detection zone for a scannerless optical rangefinder operating in pulsed Time-of-Flight operation are described. The method comprises pulsating a light source to illuminate the detection zone using an emission beam; receiving a reflection from the detection zone, collecting the reflection using an optical detector and generating a reflection signal; discretizing the detection zone to create a predetermined detection pattern in the detection zone, the predetermined detection pattern being one of regular, uniform and random, the predetermined detection pattern including passive areas and discrete active detection areas within the detection zone; detecting an object in one of the discrete active detection areas by comparing a change in the reflection signal with a background signal.

Abstract: A power supply charger for charging battery cells divided into at least two battery cell groups, each battery cell group having an associated protector circuit module. The power supply charger comprises, for each battery cell group, a power converter, a constant-current and constant-voltage device connected to the power converter for selectively applying a voltage from the power converter across the battery cell group and a current sensing circuit. The power supply charger further comprises, for each battery cell of a battery cell group, a voltage sensing circuit and a balancer circuit. Finally, the power supply charger comprises a micro-controller operatively connected to the various components and is so configured as to, for each battery cell group, selectively apply a voltage across the battery cell group or decrease the voltage of individual battery cells in the battery cell group in response to sensed battery cell voltage and battery cell group current.

Abstract: A power supply charging method and device for charging a power supply having a predetermined number of battery cells divided into at least two battery cell groups. The method comprises the steps of, for each battery cell group, applying a voltage across the battery cell group until one condition selected from the group consisting of the voltage of a battery cell exceeding a first threshold and the current of the cell group dropping below a second threshold, is met and verifying that each of the predetermined number of battery cells has a similar voltage. When the verification of the battery cells voltage determines that at least one battery cell has a voltage departing from the voltage of the other battery cells by more than a predetermine value, the voltage of the other cells is decreased and the previous steps are repeated.

Abstract: A firearm includes a frame, a slide, and modular sear and trigger mechanism housings. The frame has fore and rear receptacles integrally formed therein, e.g., upwardly open compartments accessible from the top of the frame. The modular housings house one or more operational components of the firearm, e.g., trigger and sear components, and are configured for “drop in” insertion into the receptacles. Each housing also includes a set of integral slide rails. For assembly, the operational components are attached to the modular housings, and the housings are dropped into the receptacles and secured to the frame. The slide is operably positioned on the slide rails for reciprocating movement thereon. The frame is provided without integral rails and other features for supporting the operational components. Instead, the rails are provided as part of the modular, drop-in sear and trigger mechanism housings, which also support the operational components.

Abstract: A configurable firearm grip is provided in which a removable portion thereof can be selected by the user based on the user's preference. For example, backstraps of various forms, thicknesses, and textures can be fitted to a handgun depending upon if the handgun is to be used for target shooting, competitive target shooting, hunting, personal protection, or any other shooting activity, or to accommodate varying hand sizes. The backstrap can be removed and installed without the use of tools. Cooperative portions on the inner surfaces of the backstrap and the rearward portion of the grip facilitate the registration of the backstrap with a fixed portion in preparation for the insertion of a locking element. The backstrap is able to be secured on the fixed grip portion of the handgun with one hand while the locking element is inserted through the backstrap and the fixed grip portion with the other hand.

Abstract: A method for mounting a substrate having a first image printed thereon on a digital printer to be used to print a second image in a desired alignment with the first image, wherein the first image is printed on the substrate using a nondigital process. The first image is related to a second image to form a composite image. First, registration holes in a template are placed over registration pins on the digital printer, thereby mounting the template on the printer. The second image is printed on the template using the digital printer, and the template is then removed from the digital printer. Registration holes of substrate leaders and the registration holes of the template are placed over registration pins extending from a work surface. The substrate is then positioned with respect to the substrate leaders and the template at a desired location where the first image on the substrate aligns with the second image on the template. The substrate leader is then secured to the substrate at the desired location.
