Abstract: Disclosed are techniques for wireless communication. In an aspect, a user device may establish a device-to-device communication with a point of interaction (POI) device based on a distance between the user device and the POI device being within a reference distance. The user device may engage in an authentication procedure with the POI device via the device-to-device communication to verify authenticity of the POI device. The user device may send transaction data to the POI device via the device-to-device communication after the authenticity of the POI device is verified. The user device may terminate the device-to-device communication after the transaction data is sent to the POI device.

Abstract: Hydraulic axial piston unit having a rotational group for driving or being driven by a driving shaft, and a tiltable displacement element for adjusting the displacement volume of the rotational group. The rotational group includes a rotatable cylinder block in which working pistons are mounted reciprocally moveable in cylinder bores for conveying hydraulic fluid from an inlet port to an outlet port on a valve segment. At least two control ports are located on the valve segment each between the inlet port and the outlet port. The control ports can be brought sequentially in fluid connection with the cylinder bores when the cylinder block is rotating. At least one hydraulic fluid injector is connected fluidly to one control port, for sequentially injecting pressurized hydraulic fluid via the control port into the passing cylinder bores. Via the other control port hydraulic fluid can be drained from passing cylinder bores.

Abstract: Hydraulic axial piston unit having a rotational group for driving or being driven by a driving shaft, and a tiltable displacement element for adjusting the displacement volume of the rotational group. The rotational group includes a rotatable cylinder block in which working pistons are mounted reciprocally moveable in cylinder bores for conveying hydraulic fluid from a kidney-shaped inlet port to a kidney-shaped outlet port on a valve segment. At least two control ports are located on the valve segment each between the respective circumferential ends of the kidney-shaped inlet port and the outlet port. The control ports can be brought sequentially in fluid connection with the cylinder bores when the cylinder block is rotating. At least one hydraulic fluid injector is connected fluidly to one control port, for sequentially injecting pressurized hydraulic fluid via the control port into the passing cylinder bores. Via the other control port hydraulic fluid can be drained from passing cylinder bores.

Abstract: A shoulder strap is provided with raceway provisions for medical tubing. The shoulder strap has opposite ends provided with male and female side-squeeze buckles. The raceway provisions are formed by an inner leaf and outer leaf which fold and fasten together for safely enclosing the medical tubing. The medical tubing extends between a nose piece and a connector end, wherein excess length of the medical tubing is usually coiled up in coils near the connector end. The shoulder strap further includes tubing traps which safely secure the coils. The tubing trap can be formed from snaps, buttons and/or hook-and-pile fastener material. The inner and outer leaves of the shoulder strap can be formed of any suitable material, such as that used in book bags except also provided with foam (cushion) cores.

Abstract: A latch assembly is provided, the latch assembly having: a chassis, a latch bolt having a closed position and an open position, a pawl having an engaged position and a disengaged position, an eccentric arrangement defining an eccentric axis and a pawl axis remote from the eccentric axis, wherein when the pawl moves from the engaged position to the disengaged position the eccentric arrangement rotates about the eccentric axis to move the pawl axis from a first pawl axis position to a second pawl axis position, a retaining mechanism having a retaining position at which the pawl axis is held in the first pawl axis position and having a non-retaining position at which the pawl axis is allowed to move to the second pawl axis position, a release lever configured to move the retaining mechanism between the retaining position and the non-retaining position.
