Abstract: The electrical connector unit includes a first connector electrically coupled to a component to define a path for electrical supply therethrough for an activation and a deactivation of the component. The first connector includes a body, electrical contacts, and an opening. The body includes a surface that defines an array of electrical contact locations including one or more first electrical contact locations and a second electrical contact location. The electrical contacts extend correspondingly from the first electrical contact locations. The opening extends from the second electrical contact location to fluidly couple with an interior of an enclosure encasing the component. The first connector is configured to receive a second connector configured to facilitate passage of a fluid through the opening to create a pressure differential between the interior of the enclosure and an exterior of the enclosure for performing a leak testing of the enclosure.

Abstract: An inflation device system incorporates and internal valve. The incorporation of an internal valve allows for more precise application and measurement of gas pressure with in an object to which the inflation device is inserted. The valve may be a Schrader valve.

Abstract: Systems, devices and methods are described herein that are configured for use in the monitoring and detecting of chemical reactions, such as, for example, the monitoring and detection of Polymerase chain reactions (PCR). For example, the systems and devices described herein can be used for accelerated real-time PCR. A fully integrated PCR system is provided that includes a touch screen user interface, eliminating the need for additional computers, keyboards, and related devices. The PCR systems described herein can be network enabled to provide communications between one or more PCR monitoring and detection devices and a central monitoring station. A disposable sample holding device can be placed in the PCR device for testing in an upright vertical orientation, providing improved optical scanning capabilities and rapid heating and cooling capabilities.

Abstract: A new latch hook for permitting secure hanging of strapped bags, such as purses and backpacks, to help prevent easy removal by thieves. The inventive device includes a mounting plate, a hook body, and a latch member. The root of the hook body is coupled to the mounting plate while the tip of the hook body is spaced apart from the mounting plate. The hook body also has a lower arcuate portion positioned adjacent the tip of the hook body. An arcuate inner hooked portion positioned adjacent the lower arcuate portion of the hook body is extended from the hook body towards the mounting plate. The upper end of the latch member is pivotally coupled to the hook body between the root of the hook body and the inner hooked portion such that the latch member extends toward the tip of the hook body.
