Abstract: In one example, a tie-down apparatus can include a tie-down device and a housing adapted to receive the tie-down device. The tie-down apparatus can be transitionable between a stowed state and a deployed state. In the stowed state, the tie-down device can be stored entirely within the housing. The stowed state can be convenient for storing the tie-down device when not in use. In the deployed state, certain portions of the tie down device can be concealed within the housing while other portions of the tie-down device (e.g. attachment mechanisms) are deployed through openings in the housing. The deployed state can be convenient for securing cargo without damaging (e.g. scratching or denting) the cargo.

Abstract: A programmable network-DTE interface integrates T1/E1 framer, data pump and microprocessor components into a common subsystem chip architecture, and interfaces each of these components by means of a user programmable multiplexing subsystem, so as to allow any of the functional blocks of the architecture to be selectively enabled or disabled/by-passed by the user.

Abstract: A shared T1/E1 signaling bit processor interfaces with either T1 or E1 traffic, and controllably performs robbed bit signal extraction and insertion for T1/E1 signaling protocol using a common set of input/output circuitry and associated decode/control logic therefor. A receiver subsystem controllably samples and extracts signaling bits from selected time slots within serial frames of data incoming from the network to the DTE for delivery to the control processor; a transmitter subsystem controllably inserts signaling bits into selected signaling channels of serial frames of data outgoing from the DTE to the network.

Abstract: A transmission strobe clock signal control mechanism continuously monitors DTE data and transmission strobe clock signals used to strobe the DTE data onto a serial communication link, and automatically adjusts the phase of the transmission strobe clock signal in response to a misalignment between the two signals that exceeds acceptable limits. In a first embodiment, the DTE data signal is sampled by a high speed clock and clocked through a `data sample` shift register. Selected stages of the register, associated with a timing window that contains a transmission strobe clock signal edge, are coupled to an exclusive logic operation circuit, whose output indicates whether all of the data samples in the selected stages of the shift register are the same or not. If not, it is inferred that a data transition too close to the transmission strobe clock signal edge has occurred, necessitating an adjustment of the phase of the transmission strobe clock signal.
