    In scme radios, a battery saver mode for PL was not enabled due insignificant current savings. The sleep period was only 60 msecs and the active time was about 450 msecs. The battery save period is about 12%. This figure was not optimal and could be improved to 84% and more.

    A portable radio which offers channel selection option requires some type of selector switch to facilitate access. The selector switch shown (Figure 1) serves the purpose mechanically. This switch consists of: (i) contact finger (ii) return spring (iii) slider (iv) housing These four components form a selector switch...

    In the Secure Telecommunications business there exists a need for special function modules to accom- pany the end user's telephone. These special function modules must attach mechanically and electrically to the phone in a way that allows for flush mounting. In doing so, the electrical interconnection must 1) be...

    Lightly-doped drain (LDD) structures are typically used to suppress hot-carrier effects in submicron CMOS devices [ 11. The conventional LDD spacer process con- sists of a low-dose source/drain implantation performed after polysilicon gate etch which is followed by the dep- osition and reactive-ion etch of a...

    This invention allows multiple power devices to be tkmly secured against a heatsink by means of a single spring clip panel. By reducing parts count, this inven- tion drastically improves an assembly's manufacturabiity. Also, the invention circumvents the need for vibration supports and chemical adhesives, which can be...

    As mechanical shock performance expectations increase in personal communication devices, improved methods of shock isolation are needed to satisfy these demands. Existing designs utilize boots or snubbers formed from butyl or silicone to enclose shock sensitive components (i.e.: quartz, ceramic components). This...

    Microcell systems are currently operating in many countries around the globe. With the large amount of base stations distributed around cities, there are times when more than one base station is in range of a user. When the user tries to place a call in an environment where they are in range of more than one base...
