Abstract: Ear-piece type acoustic transducing part is provided with a bone-conducted sound pickup microphone for picking up a bone-conducted sound, a directional microphone for picking up an air-conducted sound and an electro-acoustic transducer for transducing a received speech signal to a received speech sound. A transmitting-receiving circuit connected to the acoustic transducing part includes: a low-pass filter which permits the passage therethrough of low-frequency components in a bone-conducted sound signal from the bone-conducted sound pickup microphone; a high-pass filter which permits the passage therethrough of high-frequency components in an air-conducted sound signal from the directional microphone; first and second variable loss circuits which impart losses to the outputs from the low-pass filter and the high-pass filter, respectively; a comparison/control circuit which compares the output levels of the low-pass filter and the high-pass filter with predetermined first and second reference levels, respectively, and based on the results of comparison, controls losses that are set in the first and second variable loss circuits; and a combining circuit which combines the outputs from the first and second variable loss circuits into a speech sending signal.

Filed: 1995-09-28
Abstract: 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.

Title: Custom class selection in automated mail processing
Inventor: KULIK GEORGE
IPC: G07B17/00
Filed: 1997-02-24
Abstract: A program controlled automatic mail processor includes custom rates software to facilitate processing of mixed mail streams for posting via a plurality of classes, without manual sorting of the mail into classes or manual selection of classes during mail processing.  A user defines a custom rates template, specifying classes and break point parameters (e.g. weight values) for controlling shifts between the selected classes.  The mail processor uses the template and previously stored standard postage rate tables to develop a custom rates rate table for processing mail in multiple classes.  Once the custom rates rate table is established, an operator can select any table from among the standard tables and one or more such custom rates rate tables.  The operator then begins feeding mail through the mail processor.  The mail processor checks a parameter value (e.g. weight) of each piece of mail and applies the appropriate postage value from the currently selected table.  In particular, if the user selects a custom rates rate table, the mail processes pieces of mail in a single stream in multiple mail classes, using class break point or classification information and corresponding rate information from the custom rates rate table.

Title: Electrotransport delivery device
Inventor: MCNICHOLS LARRY A
IPC: A61N1/30
Filed: 1995-11-27
Abstract: An electrotransport delivery device (410) includes control circuitry for discontinuously delivering a beneficial agent (e.g., a drug) through a body surface (e.g., skin 400). For example, the device may be the type which is manually activated by the patient or other medical personnel to activate electrotransport drug delivery. Once electrotransport delivery has been activated, a timer (221) counts a transition interval, typically about one minute, during which the device is allowed to operate and the impedance of the body surface (400) is allowed to stabilize.  Thereafter, the electrotransport current and voltage are then monitored and compared to predetermined limits. Allowing for the transition interval permits tighter tolerances in monitoring the applied current.
