Abstract: A system and method dynamically schedule wireless transmissions without collision. A master transmitter periodically transmits a time mark during a first predefined time slot of a plurality of consecutive time slots that form a transmission block. Multiple consecutive transmission blocks form a frame. An announcement transmission from a wireless transmitting device is received via at least one receiver during a second predefined time slot of the plurality of time slots. An allocator allocates, at least partly based upon the received announcement transmission, a third time slot of the plurality of time slots to the wireless transmitting device. A time slot reservation area of at least one subsequently transmitted time mark includes indication of the allocation of the third time slot to the wireless transmitting device. The wireless transmitting device receives the subsequently transmitted time mark and transmits only during the third time slot of subsequent frames.

Abstract: Disclosed is a way of mounting cylinders on the outside of the packer head of a compactor. With this disclosure the cylinders as well as guides may be much easier and faster to change or service resulting in less downtime for the owner and less costly repairs.

Abstract: A pneumatic motor trigger actuator includes a trigger housing adapted to engage a pneumatic motor trigger of a pneumatic tool. A top plate is coupled to the trigger housing. A primary valve is coupled to the top plate and has an open configuration and a closed configuration. The primary valve is pneumatically coupled to the trigger housing such that air flow through the primary valve, when the primary valve is in the open configuration, enters the trigger housing and causes a plug to physically engage the motor trigger with sufficient force to move it to is fully engaged position. The primary valve includes a primary switch and an automatic stop switch. The primary switch is engagable by an operator to configure the primary valve in the open configuration. The automatic switch is engagable by an object to move the primary valve to the closed configuration when a predetermined condition is met.

Abstract: A drill clamp comprising a clamp mechanism and a hole-locating pin. The clamp mechanism has a first clamp portion and a second clamp portion. The second clamp portion includes a drill-receiving opening sized for receiving a drill bit. The hole-locating pin is operatively connected to the first clamp portion. The clamp mechanism is adapted and configured for movement of the first and second clamp portions relative to each other between clamped and unclamped positions. The hole-locating pin is farther from the drill-receiving opening when the clamp mechanism is in the unclamped position than when the clamp mechanism is in the clamped position. The hole-locating pin and the drill-receiving opening are aligned with one another when the clamp mechanism is in the clamped position.
