Abstract: A wheel fastener alarm assembly is provided having a fastener body with a first portion defining a wrenching surface and a cavity, and a second portion with a threaded portion to attach and detach from a wheel of a vehicle. A sensor array is disposed in the cavity of fastener body to detect an attribute of the fastener body and generate an output signal based on the attribute of the fastener body. An antenna connected to the sensor array to transmit the signal to a remote location. A cap is secured to the first portion of the fastener body and covers the wrenching surface and the cavity opening to define a capped fastener body.

Abstract: The present disclosure provides acyltransferases useful for synthesizing therapeutically important statin compound.

Abstract: A system and method for measuring latency in voice communications is presented. In an exemplary embodiment, latency is measured by establishing a call between a first and a second telephony device, and measuring a latency between a signal originating at the first telephony device and the signal as it arrives at the second telephony device.

Abstract: This invention relates to an electrical caulking gun utilizing a triggering mechanism that controls both the mechanical and electrical operations of a plunger unit that applies axial pressure against a caulking cartridge. The triggering mechanism sits in a grooved channel in a caulking cartridge receptacle and comprises of a trigger rack with a series of wedges on its top and a gear rack, which lies atop the trigger rack, with a series of reciprocating wedges on its bottom that meshes with the wedges on the trigger rack. The wedges on the trigger rack and gear rack cooperate with each other to push the gear rack upward when the trigger rack is moved rearward. The gear rack has a series of gears on its top such that, when pushed upward, they will engage with a drive gear protruding from the plunger unit. The drive gear drives the plunger unit, and is in turn driven by an electrical motor in the plunger unit. The trigger rack, when pulled rearward to its maximum position, will activate the electrical motor.
