An orbital hold-down clamp assembly holds a workpiece in place on a platen against a stop or backjaw on the platen. The clamp assembly has four main parts. A screw cam has a threaded shaft and an offset tapered head; a clamp jaw has a distal gripping surface and a foot or fulcrum at the proximal edge; a flat rubber spring is positioned beneath the clamp jaw; and a T-nut mounts in a nest in the platen. The clamp jaw has a tapered opening that matches the taper of the cam head. The nut has a threa...

The bus hold circuit comprises: an input stage inverter (IN1) connected between a first supply voltage (Vcc) terminal and a second supply voltage (Vss) terminal and including: a first P-channel transistor (P1); and a first N-channel transistor (N1) connected in series to the first P-channel transistor, a gate of the first P-channel transistor and a gate of the first N-channel transistor being connected in common to a bus line (INA); and an output stage inverter (IN2) also connected between the f...

An on hold telephony service that allows a subscriber to the service to place a call on hold and make interactive games available to the party placed on hold. The on hold service can be implemented on a central office switch or an enhanced services platform connected to the switch. The on hold service is accessed by the subscriber to the service through a transfer function that causes the call to be maintained by the on hold service. The party so placed on hold by the subscriber can then interac...

A telephone includes a telephone body, a handset and a telephone network line hold mechanism. The telephone body includes a handset cradle on which the handset is placed, a plurality of operation buttons and the like. The telephone is placed in the offhook state when the user lifts the handset from the handset cradle and placed in the on-hook state when the user places the handset on the handset cradle. The telephone network line hold mechanism is energized when the user places the handset on th...

Apparatus and a method of implementing a notification and hold service in a telephone network is disclosed. A calling telecommunications device is placed on hold by the called telecommunications device, and signals an auxiliary computer system through a network switch that the calling telecommunications device is to be disconnected from the called telecommunications device. The calling telecommunications device is notified at a later time that the called telecommunications device is no longer on...

An automated telephone hold device including a housing with a visual indication mechanism, audible indication mechanism, and push button switch positioned on a top face thereof. Further included is a voice playback mechanism, decoder, phone interface, and sequential logic located within the housing. In use, the sequential logic allows a user on hold to depress the push button switch which, in turn, actuates the visual indication mechanism. At this point in time, the phone interface allows commun...

A method and system for sampling an analog signal that minimizes perturbations caused by noise. In one embodiment, the sample and hold circuit includes a plurality of switches in series between the sampled source and a hold capacitor. A resistor is located in parallel with the first switch. The two switches are controlled so as to provide three signal paths between the hold capacitor and the sampled signal. The first signal path is a closed circuit between the charge capacitor and the sampled si...

The present invention relates to an adjustable hold-down assembly for securely holding heavy and/or bulky goods such as automobile seats to a shipping pallet for transportation thereof. The shipping pallet has a base and a hold-down assembly and which has a cross-bar positioned between two securing posts that are movably attached to the base. The cross-bar is configured for rotational movement relative to the base and linear movement with respect to the securing posts.

A clip to hold panels in place in grid openings in a suspended ceiling. The clip is integrally formed and includes relatively flexible hinges that bias relatively rigid sections against the panels.

A method, system and product for managing a hold queue is provided. A call center receives an incoming telephone call from at least one caller and places the caller in an initial position in the hold queue. When a caller is in a hold queue at a call center, a request can be made to pause the caller's position in the hold queue. When the caller is ready to return to the hold queue or when the pause duration has expired, the caller becomes active in the hold queue.
