19 Sep 2000TL;DR: An internet radio for portable applications and uses such as in an automobile is described in this paper, which allows access to a host of audio, visual and other information, such as stock quotes, travel information, advertising, and e-mail.
Abstract: An internet radio for portable applications and uses such as in an automobile. The internet radio allows access to a host of audio, visual and other information. Normal radio channel function is provided along with programmable content and channel selection, as well as automatic content and channel updating by location and style. Internet access is also provided. Direct or targeted advertising, as well as electronic commerce is supported. Connection to the internet is through wireless communications. Programmability is achieved off-line via a web page and remote computer. Customized information is also communicated to the radio such as stock quotes, travel information, advertising, and e-mail. Onboard global positioning allows for channel updating by location, traffic information, geographic advertising and available similar content.

20 Sep 1996TL;DR: A hybrid energy storage system as mentioned in this paper includes a first energy storage device, such as a secondary or rechargeable battery, and an electrochemical capacitor, which provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices.
Abstract: A hybrid energy storage system (10) including a first energy storage device (12), such as a secondary or rechargeable battery, and a second energy storage device (14), such as an electrochemical capacitor. The electrochemical capacitor provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices. Such devices typically require power pulses in excess of those which conventional battery cells can easily provide for numerous cycles. The first and second energy storage devices may be coupled to output electronics to condition the output of the devices prior to delivering it to the application device.

TL;DR: A conclusion is reached regarding a new protocol combination which is found to offer significant advantages over all other protocols explored and which may be suitable for use on the land mobile radio channel.
Abstract: An important problem in land mobile radio communications is how to provide reliable data communications to the largest number of users. To explore this problem, several existing ARQ protocols are examined which have application to the land mobile radio channel, as well as some new protocol combinations. All protocols are analyzed for several key system performance measures which are verified by experimental means for static as well as fading channels. Finally, a conclusion is reached regarding a new Protocol combination which is found to offer significant advantages over all other protocols explored.

22 Mar 1993TL;DR: In this paper, a lead frame is used to support a semiconductor die to alleviate package cracking problems caused by stress and to provide a universal lead frame which is suitable for use with many different die sizes.
Abstract: A semiconductor device (10) includes a lead frame (12) having tie bars (16). In one form of the invention, the tie bars are used to support a semiconductor die (20) to alleviate package cracking problems caused by stress and to provide a universal lead frame which is suitable for use with many different die sizes. In another embodiment, a semiconductor device (45) includes a lead frame (40) having a mini-flag (42) to accomplish these same objectives.

24 Jul 1992TL;DR: In this paper, a method and apparatus for encoding and decoding of orthogonal codes is presented. But the method is not suitable for the decoding of large numbers of samples, and it is difficult to find a suitable encoding scheme for such groups.
Abstract: A method and apparatus is provided for encoding and decoding. In encoding, bits (202) are encoded (204) into symbols (206) such that maximum likelihood decoding is facilitated. Groups of symbols (206) are translated by either interleaving by group each group within a block (208) and subsequently deriving an orthogonal code from each group (212) or deriving an orthogonal code from each group and subsequently interleaving by code each code within a block. In decoding, groups of samples (228, 229) are transformed by either generating metrics and index symbols (242) for each group of samples (232, 234, 236, 238, 240) and subsequently deinterleaving by group each group of metrics within a block (244) or deinterleaving by group each group of samples within a block and subsequently generating metrics and index symbols for each deinterleaved group of samples. Each metric represents the confidence that a group of samples is a particular orthogonal code. Subsequently, maximum likelihood decoding (266) generates an estimated bit (268) from the index symbols and metrics (260).
