Abstract: This invention is for safely speeding up the rewinding of a strap used to secure cargo on a truck or trailer. The Tool consists of a shaft which in use extends into the inside of a conventional strap winch drum. At the end of the shaft is a cylindrical elastomeric plug which is a tight fit into the inside of the winding drum. The shaft is then connected to a rotary drive apparatus comprising a hand crank or is power driven. Because the tool can be simply pushed into the drum and operated without the requirement of alignment of the shaft, for a mechanical connection between the shaft and winch drum, the operator's hands need not be on the tool other than on the handle which is not above the drum. This is typically quicker and safer than the prior art.

Abstract: A system for testing wireless communication equipment which includes a beamforming antenna, the system comprising: a probe for coupling an antenna element of the beamforming antenna of the wireless communication equipment to be tested to a test and measurement unit; and a lid configured to cover the beamforming antenna, wherein the lid is provided with a port for receiving the probe, such that the probe couples to the antenna element.

Abstract: A base station testing system may receive one or more input signals originating from one or more transceivers of a base station. The base station testing system may form, based on the one or more input signals, one or more output signals associated with a beam direction. The base station testing system may provide a feedback signal, that is based on the one or more output signals, to a calibration component of the base station.

Abstract: Improved exercise assemblies and related methods of use are provided. More particularly, the present disclosure provides advantageous exercise assemblies that are adjustable, changeable and/or rotatable. The present disclosure provides for an exercise assembly that can function as a straight pull-up bar in one arrangement, and can also function as a dynamic, range-of-motion exercise assembly in another arrangement. The exemplary exercise assembly includes an advantageous design that permits users to not only perform straight bar pull-ups, but also allows users to quickly and easily convert the assembly into a two-handled, variable resistance, bicycle-style crank (e.g., a rotating bicycle pull up bar assembly) in which the user rotates two handles of the bar similar to how a cyclist rotates bicycle pedals.

Abstract: A conveyor pan is provided for supporting a portion of a mining conveyor extending along a mine face and positioned between the mine face and a goaf. The conveyor pan includes a deck, a toe, and a heel. The deck includes a first side configured to be positioned proximate the mine face and a second side configured to be positioned proximate the goaf. The toe is positioned adjacent the first side of the deck, and includes a toe contact surface defining a toe surface area. The heel is positioned adjacent the second side of the deck, and includes a lug and a heel contact surface. The lug is configured to be coupled to an advancement mechanism. The heel contact surface defines a heel surface area greater than the toe surface area.

Abstract: A longwall mining machine and a linepan section, the linepan section may include a face-side rail, a gob-side rail opposite the face-side rail, and a conveyor pan between the face-side rail and the gob-side rail. The face-side rail may have a generally horizontal top surface at a top surface height and with a top surface width, an angled loading surface extending toward the mining face and the ground surface and arranged at an oblique angle relative to the top surface, the loading surface being at a loading height and with a loading surface width, the loading surface width being at least about 25 percent of the total width, and a material cavity defined in the face surface below the loading surface and recessed toward a gob-side.

Abstract: A system and method for enabling verification of billing data received from an operator of a network resource access gateway by a billing service provider. An access gateway device is coupled to a network user device and to a billing service provider's system. The network user device generates billing data. The access gateway device is configured to compare received billing data with corresponding billing data generated by the access gateway device and if the received billing data correlates to the billing data generated by the access gateway device, the access gateway device stores portions of the received billing data.

Abstract: A Network Resource Trading Exchange which allows Access Gateway Operators (who are usually also Network User Device Users) to trade usage of Network Resources (e.g. Internet access) via their Access Gateway for usage of Network Resources via other Access Gateway Operators' Access Gateways. Owners of Internet-connected wireless Access Gateways are enabled to trade Internet access via their own infrastructure for roaming access via other Access Gateways anywhere in the world. Access Gateway Operators can use their underutilized Network Resources to pay for Network Resource usage elsewhere, without having to purchase any subscription or pre-payment plan.

Abstract: Ripcord pins secure a parachute pack and, on removal, allow the parachute to be deployed from the pack. Such pins are provided with indicating means that provide an indication, such as a visual indication, that the pin has been bent. This avoids the re-use of straightened pins that may break in use.

Abstract: A communication system for a distributed locomotive power/brake control system for a railroad train having a lead locomotive and one or more remote locomotives. Command and status signals are communicated over the system between the lead and remote locomotives. Each communicated message includes an information segment comprising the command or status information, and an error control segment for detecting errors in the information segment. The error control segment further comprises cyclic redundancy code words and parity bits formed according to the horizontal or vertical parity of the information segment and the cyclic redundancy code words.

Abstract: A low noise sinusoidal signal at a desired output frequency is synchronised using a first variable frequency oscillator (1) and providing a feedback control loop around the first oscillator (1) to generate a feedback control signal in successive frequency comparison steps using second and third frequency reference signals (44, 42). Each of the second and third frequency reference signals are derived from a first frequency reference signal, the second frequency reference signal (44) being compared with the output frequency of the first oscillator (1) to generate a frequency difference signal (43), and said frequency difference signal (43) being compared in frequency with the third frequency reference signal (42) to generate said feedback control signal for the first oscillator (1), the frequency of the third frequency reference signal (42) being equal to the difference of the frequency of the second frequency reference signal (44) and the desired output frequency.
