An ergonomic and weatherproof hand-held electronic device. The deviceincludes a housingwhich surrounds internal electronics. An inputand a display screenare mounted on the housing. The housingis has a narrow width such that, when held in a hand, the thumb of that same hand may extend fully across the inputfor full access. The display screenis mounted vertically below the inputsuch that the device may be more stable and more easily grasped. The device includes two cylindrical cavitiesto receive batteries. The cavitiesare located at the rear vertical edges of the housing such that the rear of the housingis relatively rounded and thus easier to grasp. The battery cavities open to the exterior of the housing. A battery coveris mounted to the housing and seals the cavities. A contact for each cavityis located on the cover, and a bus bar extends between the contacts to complete the circuit between the batteries

A portable electronic device is provided which includes a housing having a front face, a base, and a back wall joined in a polyhedron configuration. The front face includes an input area having keys for data entry and a display area having a screen to illustrate information to the user. The front face, back wall, and base are joined in the polyhedron configuration, such that the front face is presented to the user at an angle to horizontal when the base is mounted upon a horizontal or vertical surface. The front face, back wall, and base are joined at rounded edges to afford a smooth contour which is easily and comfortably grasped within the hand of the user. The portable electronic device further includes a sensor to determine whether the housing is aligned upon a horizontal or vertical axis. This sensor delivers its output to a display control which realigns information displayed upon the view screen to shift the displayed information between vertical and horizontal configurations. The input keys within the input area include indicia identifying the function of each key, wherein the indicia are aligned at an angle with respect to the longitudinal axis of the housing. Such angular alignment of the indicia enable the indicia to be easily viewed when the housing is held within the hand of a user at a vertical alignment or mounted upon a console in a horizontal alignment.

An ergonomic and weatherproof hand-held electronic device 10. The device 10 includes a housing 12 which surrounds internal electronics. An input 28 and a display screen 32 are mounted on the housing 12. The housing 12 is has a narrow width such that, when held in a hand, the thumb of that same hand may extend fully across the input 28 for full access. The display screen 32 is mounted vertically below the input 28 such that the device may be more stable and more easily grasped. The device includes two cylindrical cavities 48 to receive batteries 42. The cavities 48 are located at the rear vertical edges of the housing such that the rear of the housing 12 is relatively rounded and thus easier to grasp. The battery cavities open to the exterior of the housing. A battery cover 54 is mounted to the housing and seals the cavities 48. A contact for each cavity 48 is located on the cover, and a bus bar extends between the contacts to complete the circuit between the batteries 42.

A GPS frequency converter is provided, according to the present invention, to down-convert the frequency of an incoming GPS signal. The converter includes first and second mixers, the former of which receives the incoming RF signal and a signal from a local oscillator. The local oscillator signal is increased by a factor of 98 and then subtracted from the incoming RF signal to produce a first intermediate frequency signal (IF). The first IF signal is then passed to the second mixer which subtracts the frequency of the local oscillator therefrom to produce a second intermediate frequency signal (IF). The second IF signal is passed through a limiter and output as the frequency converted signal.

An electro-optical display device having an improved connector arrangement. The display device includes a plurality of pixels arranged in commons and segments, with a lead trace associated with each commons and with each segment. These lead traces extend outward from an endmost commons to an edge of the device for subsequent connection to driving apparatus. The set of leads associated with the set of commons extends normally from such set of commons to the proximate edge of the device. The remaining set of leads, associated with the segments, is provided with lead traces which are redirected to also extend towards this same side of the device. As such, all leads for the device are accessible on a single side of the device. This may be accomplished by dividing the remaining set of commons in half, with each of these half-sets of leads being directed to a location on an associated side of the initial leads for the first set of commons. In this manner, a single connection is required between the device and the driving equipment, with such a connection typically being capable of formation by a low cost heat seal.
