A firearm laser training system of the present invention includes a laser transmitter assembly, one or more actuable target assemblies each having a target, an interface unit and a computer system. The target assemblies raise and lower targets in accordance with control signals from the computer system. The interface unit is connected to the target assemblies and the computer system and transfers signals therebetween. In an alternative embodiment, the computer system is connected to a control unit that transmits control signals received from the computer system to the target assemblies via a distribution unit. The targets are raised by corresponding target assemblies at prescribed times for a specific time interval to indicate intended targets for the user, and are lowered in response to the beam impacting the raised targets within that interval (e.g., indicating a hit) or upon expiration of the interval without a beam impact (e.g., indicating a miss).

The present invention is remote control system including one or moree portable units and a base unit which employs identifiction codes for security. The operator preferably can select the identification code for the base unit, preferably via a process yielding a random number, with a provision for selection of a predetermined reset code. The base unit teaches this identification code to a portable unit via mating asynchronous communication ports. The same identification code may be taught to plural portable units. This identification code is stored in a static random access memory in the portable units and in an electrically erasable read only memory in the base unit and this is not susceptible to determination by visual inspection. Each portable unit includes a capacitor for storing energy so that the battery, which ordinarily supplies electrical power to the portable unit, can be replaced without loss of the stored identification code. Each portable unit may have plural buttons and plural memories enabling a portable unit to operate a plurality of base units. This may also enable a single portable unit to control a plurality of operations of a single base unit.

The present invention is an automatic garage door operator with a two button portable controller enabling a secure mode and control of a load remote from the door operator. In accordance with the normal operation of the secure button, actuation when the garage door is closed toggles a secure mode between secure and non-secure states. In the secure state the automatic garage door operator does not move the door upon receipt of a door signal. To open the door when in the secure state the operator must first press the secure button to enter the non-secure state and then press the door button to open the door. The secure button has a secondary function when the garage door is open and the secure state is prohibited. Actuation of the secure button when the door is open toggles the state of a load remote from the automatic garage door operator between an on state and an off state. This control is achieved via a signal modulated on the electric power main.

Attachment of a ring, particularly a metal ring (2), to an article which has walls or skirts (1) of fibre-reinforced resin material. The ring has a plurality of external grooves (3, 4, 5, 6). The skirt comprises, for each groove in sequence, a first (32, 36, 37, 40) and second (33, 38, 39, 41) layer of fibre-reinforced resin material. The fibres in the first layer have a substantial orientation in directions parallel with the axis of the ring and extend from the skirt into the respective grooves. Overlying the first layer is a second layer comprising hoop windings from the skirt towards the groove. The second layer lies at least partly in the groove to lock the first layer in the groove. This layering is repeated for each groove and finally successive hoop windings (45, 46, 47, 48) are wound over the entire article. This is useful for attaching end rings to rocket motor cases or for attaching rings to pressure vessels to define an aperture.

Sound attenuation devices are provided that may be temporarily worn in a person's ear. The devices generally include a first flange that is configured to be disposed in a person's ear; a second flange that is positioned proximate to the first flange and is also configured to be disposed in the person's ear (with the second flange having a proximate end that exhibits an oblong perimeter); and a cylindrical shaft extending from an interior portion of the second flange. The shaft includes an integrally connected pull tab; it extends beyond the proximate end of the second flange; and the shaft includes an integrally formed reinforcing member that spans an exterior side of the shaft and at least a portion of the pull tab. The devices further include a sound filter disposed within an internal cavity of the shaft.

A computer-based interactive fantasy sports gaming system that enables players to create a fantasy sports team for virtual participation. The fantasy gaming system implements and manages gaming sessions that correspond to and last for a single real-world sporting event. A user-interface is provided to facilitate athlete selection under constraints that limit the overall pool of athlete candidates to just those participating in the corresponding real-world event, and that limit teams to a smaller subset of the athletes participating in the real-world event. The gaming system is fully integrated with social media channels such as, without limitation, Twitter®, Google+®, and Facebook®, through which players can challenge, communicate and play with their friends.

Seat belt web retractors and associated systems and methods are described herein. Web retractors assemblies configured in accordance with various embodiments of the present technology can include, for example, a frame having a first sidewall and a second sidewall opposite the first sidewall, and a spring-loaded shaft extending between the first and second sidewalls. The web retractor can further include a locking mechanism positioned proximate to the first sidewall of the frame and operably coupled to the shaft. The locking mechanism can include a vehicle inertia sensor and/or a web inertia sensor. A cover can enclose the locking mechanism such that the cover and the first sidewall form a liquid-sealed enclosure around the locking mechanism.
