Abstract: A call path display telephone system includes an establishment telephone and a user telephone. The establishment telephone includes a memory, communication module and controller. The user telephone includes a memory, microphone, speaker, keypad, communication module, controller, and a visual input/output module. The desired menu options for a call path are visually displayed to a user to allow the user to more rapidly and efficiently navigate through the call path menu. Unlike prior-art voice based systems, it is not necessary to sequentially listen to all available options; they can be rapidly viewed visually and selected as desired.

Abstract: An antenna for integration into a portable computing device is provided. The computer includes a display mounted on a metal frame. The antenna includes a radiating element extending from the metal frame, and a conductor comprising a first component for conducting a signal and a second component connected to the metal frame for grounding the antenna.

Abstract: The present invention is directed to a computer system that has at least two computers which are connected via cordless telephone. The handset of the cordless telephone is integrated with a portable computer and the base station of the cordless telephone is integrated with a regular desktop or desk-side computer. The hand-held computer includes a microprocessor, a display, storage, a keypad to enter data, a microphone to receive voice data and speak to play voice data, and an antenna to communicate with the base station. The base station includes receiver and transmitter and an antenna, signal controller and the means for acting to a telephone system. The apparatus can be adapted for use with a television and a VCR.

Abstract: In an illustrative embodiment, the AC power line network simulator includes an enclosure for containing elements of the system. An AC coupling network coupled to the network simulator implements the functions relating to a particular simulation. A distribution panel connected to a power feed distributes power and includes outgoing circuits and circuit breakers for protecting the outgoing circuits. A plurality of outlets are connected to the breakers of the panel. Through the use of the simulator, with the AC coupling network, simulation of an AC power line network, such as measuring electrical signals, recording electrical signals, simulating electrical signals and inserting electrical signals, can be easily performed. The measured, recorded, simulated and inserted signals correspond to electrical characteristics of elements found in an AC power line network, and can be stored for later analysis. In addition, once simulation information has been stored, it can be reproduced as desired.

Abstract: A cordless modem comprises a radio pair interfaced to a standard data/fax modem which allows a user of a personal computer to wirelessly connect to a telephone line. One end of the radio pair is a remote unit interfaced to the modem contained within the PC while the other end is a base unit connected to a standard telephone wall jack. The base unit can selectively discriminate and adjust for signals received from a telephone voice handset or data signals received from the cordless modem remote unit. Upon receiving an off-hook signal or an incoming call signal, the base unit identifies the type of data (i.e., voice or computer modem data) and adapts accordingly by placing an FM modulator in either of a narrow band deviation or a wide band deviation covering the required range of the particular signal combined with local echo. That is, when voice data is present, a low deviation, narrow filter combination is selected.

Abstract: A controlled environment radio test apparatus includes first and second chambers for receiving respective first and second radio devices therein. The chambers are sized in proportion to an operational frequency of the radio devices to be tested. A signal-carrying conductor is coupled to the first and second chambers to carry a radio signal therebetween. A signal control device is connected to the radio test apparatus and configured for adjustably introducing selected signal impairments into the radio signal in order to controllably impair the radio signal. An output coupler may be provided for monitoring the effect of the signal impairments on the radio signal. An input coupler may be provided for introducing one or more perturbing signals into the radio signal. The first chamber is adapted so that transmission control inputs can be provided to the first radio device and the second chamber is adapted so that reception monitoring outputs can be received from the second radio device.

Abstract: A cordless modem comprises a radio pair interfaced to a standard data/fax modem which allows a user of a personal computer to wirelessly connect to a telephone line. One end of the radio pair is a remote unit interfaced to the modem contained within the PC while the other end is a base unit connected to a standard telephone wall jack. This arrangement allows the user the convenience and freedom of using a PC, laptop, personal digital assistant, etc., within several hundred feet of a phone jack without being encumbered by a cord. A warning alarm on the remote unit informs the user when the signal strength between the radio pair is below a threshold value. Additionally, the base unit may be equipped with two spatially separated antennas to help mitigate the effects of signal fading.

Abstract: A computer system includes a chassis having an internal connector with a first portion in electrical contact with a first external peripheral device, and second portion in electrical contact with a second external peripheral device. An adapter is coupled between an internal device and the internal connector. The internal device is associated with either the first or second external peripheral devices. The adapter has either a first portion that connects the internal device to the first portion of the internal connector or a second portion that connects the internal device to the second portion of the internal connector in order to couple the internal device to its associated external peripheral device.
