摘要:
Apparatus and a method for providing, to a service provider, telemetry access to customer equipment. The telemetry access is provided using wireless access means to avoid having to provide special residential wiring to connect to meters and control devices at customer premises. Each customer device is provided with a cellular station having its own mobile identity, either an international mobile switching identifier (IMSI) or a mobile identity number (MIN). Each IMSI or MIN need not be associated with a different telephone number. For example, a single telephone number can be assigned to a service provider to access all devices telemetered by that service provided. Advantageously, this arrangement provides for an inexpensive method and apparatus for accessing customer devices.

A method and apparatus for communicating between Customer Premises Equipment, (CPE) alarm sensing devices, and alarm monitoring stations. The sensing devices communicate with an end office switch by transmitting a message, such as a string of Dual-Tone Multi-Frequency, (DTMF) digits to that switch. At the switch, the message is processed and a determination is made which of a plurality of alarm monitoring stations should receive the alarm indication. One or more data packets are sent to the selected alarm monitoring stations with the packets identifying the source of the alarm indication, and the type of alarm indication. Advantageously, the packetized communication between the end office switch and the alarm monitoring system allows a high volume of alarm indications to be sent to an alarm monitoring station, because individual telephone connections are not required for each such alarm message.

Relates to apparatus and methods for permitting an agent of a utility or service bureau to access customer metering equipment before or during a conversation with the customer. For accessing before a call, while the customer is still on-book, an alert signal is sent to activate the telemetering equipment prior to establishing a voice connection. For accessing during the call, an alert signal is sent while the customer is off-hook. Advantageously, the measurement can be made in conjunction with the oral contact with the customer, thus making customer contacts more efficient and providing better service to customers.

The customer performs a search or otherwise defines selected data maintained by the information provider. Once the selected data is identified, the information provider maintains the requested data, typically by maintaining pointers identiying the data, but delays delivery of the requested data until the scheduled delivery time, such as a particular day and time requested by the customer or a non-peak period as determined by the information provider. When the information provider determines that delivery is appropriate, it makes a request for a suppressed ringing connection to a switching system. The switching system responds to the request for connection by creating a suppressed ringing connection where a silent alert tone or digital alert signal is transmitted to the customer premise equipment. The customer premise equipment includes a receiving system that receives one or more tones from the switching system over the suppressed ringing connection and becomes active. Upon being activated, the receiving system causes the customer's computer or portions of the computer such as a particular memory to power-up such that the computer can receive the data from the information provider.

A caller who calls an 800 number is given an audible or visual indication that the call will not incur any charges for services provided on that call by the called party. If such charges will be incurred the caller is warned and may terminate or continue the call. For certain classes of telephone subscribers such as coin stations wherein the caller is not always the same person as the one who pays the bills, calls wherein the caller may incur charges for services provided on the call are automatically routed to an operator; such calls can then be completed using credit or calling cards in order to transfer the charges from the owner of the telephone station to the caller who made the specific call.

A planar writing surface is attached to a vertically arrangable support panel for engagement next to an automobile console. The support panel has a pair of side edges which each have a vertically adjustable support leg thereon. Each support leg may be independently heightwise adjustable to each touch the floor of the auto next to the console, and provide rigidity to the writing surface. The writing surface panel may flip onto the support panel through an arc of 270 degrees, about its common hinge.

The security system includes a time dimension in an alpha-numeric personal identification number (PIN) security system to enhance its security yet maintain the familiar and simple to use PIN system. The alpha-numeric digits comprising the PIN are separated into two or more digit groups that must be entered into the system according to a predefined time sequence in order to positively identify the user and provide security clearance. The time sequence can include time delays between the entry of digit groups or time periods during which the digit groups must be entered.

An apparatus that after a time period settable by the user automatically returns an off-hook telephone to an on-hook condition. This apparatus thus electrically hangs up a telephone handset that is inadvertently left off-hook and allows normal handling of outgoing and incoming calls at other telephone extensions and in some embodiments, even allows calls to ring-in to the telephone having the inadvertently off-hook handset. The apparatus also senses when the inadvertently off-hook handset is returned on-hook and rapidly restores the automatic-return-to-an-on-hook condition switch to normal operation.

A composite tube for a gun barrel and a method for making the tube are disclosed. The tube includes a plurality of elongate carbon fibers and a resin material surrounding a longitudinal bore axis. The elongate carbon fibers are aligned parallel with the longitudinal bore axis and are under compression along the longitudinal bore axis. Such a tube for a gun barrel may be made by wrapping a tubular metal liner with a resin matrix material containing a plurality of elongate carbon fibers, and aligning the carbon fibers parallel with the longitudinal axis of the liner. The resin matrix material is cured, and the elongate carbon fibers are placed under compression along the longitudinal axis of the liner. Compressing the carbon fibers along the longitudinal axis of the liner produces a tube of surprising stiffness. The tube provides a highly stable gun barrel of reduced weight for good accuracy.
