| Number | Title | Issue Date |
| 5107259 | Means and method of displaying a message in a plurality of scripts A selective call receiver displays messages in at least two scripts. The selective call receiver receives data including an address and a message to be displayed. A decoder decodes the data and recognizes a script select character therewithin. A memory st... | 04/21/1992 |
| 5072444 | Central controller with adaptive message handling characteristics A central controller operating as a pager terminal for receiving, handling, and transmitting messages is shown that adaptively alters its message handling characteristics in order to improve the overall throughput of the central controller. The channel lo... | 12/10/1991 |
| 5068898 | Voice messaging method for selective call receivers Accelerated throughput of voice messages is accomplished by first filtering a normal 50-3000 Hz voice signal to a reduced bandwidth 350-1650 Hz (with loss of identifying features), the reduced signal then accelerated X3 and translated downward to bandwidt... | 11/26/1991 |
| 5066949 | Sending different identifiers to selected receivers, to represent the same source A method for generating alphanumeric messages in a telephone-entry selective call system comprises programmable selective call source identification for selected selective call receivers and numerically coded canned alphanumeric messages.... | 11/19/1991 |
| 5046829 | Liquid crystal display backlighting apparatus having combined optical diffuser and shock dampening properties A light guide is optically coupled to a light source and engagingly positioned between a liquid crystal display and a printed circuit board for both damping vibrations from and backlighting the liquid crystal display.... | 09/10/1991 |
| 5038466 | Multifunctional end effector and method of converting single purpose robot arm A single purpose robot arm end effector having a ring shaped frame positioned around the periphery thereof with a plurality of extendable drivers mounted in the frame for movement between a nonfunctioning position and an operative position. Each of said d... | 08/13/1991 |
| 4929910 | Low current amplifier with controlled hysteresis An improved amplifier with controlled hysteresis and an extremely low current drain capable of operating over a sufficiently large input voltage dynamic range is provided. Two circuits comprising a transistor and a diode are coupled between a differential... | 05/29/1990 |
