Abstract: An electrical connector contact has a body for receiving a conductor and for receiving a male pin contact. A spring is configured for engaging the pin contact and includes a plurality of spring fingers positioned for forming a bore with the spring fingers bent radially inwardly and configured for securing a pin in engagement with the body. A sleeve is configured for engaging the body to overlie the spring. Indentations are formed in the body at discrete positions around the body and extend radially inwardly into the pin section. The spring includes tongues extending radially inwardly and configured for extending into the indentations for securing the spring with the body.

Abstract: Apparatus and methods for selectively providing or preventing access to areas, enclosed spaces or volumes, or for controlling the position of a pivot or hinge assembly. In one exemplary embodiment, the apparatus includes a selectively actuated or actuate-able hinge which is controlled at least in part by a shaped memory alloy (SMA) filament or filaments. Application of electrical current to the filament causes changes in the physical properties thereof, thereby allowing “ratcheted” rotation of a portion of the hinge relative to other portions. In one variant, the hinge can be remotely operated, such as via wireless or wireline communication with a remote entity such as a computer or smartphone.

Abstract: Improved actuator apparatus and methodologies for manufacturing and using the same. In one exemplary embodiment, the actuator apparatus includes an SMA filament that: (1) minimizes size and increases stroke length via a serpentine-like routing of the SMA filament within the device itself; (2) reduces power consumption as a result of a relatively flat stroke force as a function of stroke displacement operating profile; (3) enables the actuator assembly to remain in a fully actuated state, at a consistent stroke force, for longer periods of time; and (4) is also fully reversible so as to be capable of use in both push-based and pull-based actuator applications. Methods of operation and manufacturing associated with the aforementioned actuator apparatus are also disclosed.

Abstract: Power-efficient actuator apparatus and methods. In one exemplary embodiment, the actuator assembly utilizes a shape memory alloy (SMA) filament driven by an electronic power source to induce movement in the underlying assembly to actuate a load (e.g., water valve). In addition, a circuit board is included which allows the actuator assembly to be readily incorporated or retrofit into a wide range of systems such that the signal characteristics of the supply line can, among other applications, be conditioned in order to protect the SMA filament. Furthermore, the circuit board can also readily be adapted for use with “green” power sources such as photovoltaic systems and the like. Methods for manufacturing and utilizing the aforementioned actuator assembly are also disclosed.

Abstract: Actuator apparatus having a multi-stable element actuated by memory alloy actuating elements. In one embodiment, the multi-stable actuator comprises a bistable (two-state) diaphragm element adapted to alternate between two stable configurations via forces exerted on the diaphragm by more than one memory alloy filaments in response to thermal activation. The bistable diaphragm element is coupled to a magnetic actuator element resident on a dry portion of a valve fitting, while a plunger actuated by the magnetic actuator element is resident on a wet portion of a valve fitting. Methods for making and using the bistable actuator apparatus are also disclosed.

In one embodiment, the multi-stable actuator comprises a bistable (two-state) diaphragm element adapted to alternate between two stable configurations via forces exerted on the diaphragm by more than one memory alloy filaments in response to thermal activation. In another embodiment, the bistable diaphragm of the multi-stable actuator transitions from a first to a second stable configuration via forces exerted by a single filament in response to direct or indirect thermal activation. A portion of the assembly is displaced when the assembly is in the second configuration. The bistable diaphragm transitions back to the first stable configuration via application of mechanical force on a portion of the assembly which was displaced. Methods for making and using the bistable actuator apparatus are also disclosed.

Abstract: An apparatus for distributing at least one product to consumers includes a housing and a plurality of belt conveyors for storing a predetermined quantity of such product. A serving tray is positioned externally to the housing for incrementally receiving one of the predetermined quantity of such product. Another belt conveyor is provided for incrementally obtaining such one of such product and for delivering it to the serving tray. A controller for selectively operating storage and delivery conveyors. A manually operable switch activates the controller to operate the delivery conveyor in order to deliver such one of such product. The apparatus is capable of capturing consumer personal data. Various methods contemplate use of these devices for delivering targeted marketing information, distributing product samples and for cross-marketing products.
