Accordingly, a virtual keypad system for inputting text is provided. A virtual keypad system includes a remote controller having at least one touchpad incorporated therein and divided into a plurality of touch zones. A display device is in data communication with the remote controller and is operable to display a user interface including a keypad, where each key of the keypad is mapped to a touch zone of the touchpad. A prediction module, in response to an operator pressing a given touch zone to select a particular character, performs one or more key prediction methods to predict one or more next plausible keys. A key mapping module remaps the touch zones of the touchpad to the keys of the keypad based on the one or more next plausible keys.

A navigation apparatus is disclosed which may be used by law enforcement personnel for rapid intervention to a location while adding safety and reliability to the process. The apparatus includes a computer system, having an operating system, memory and a user interface. The system further includes a positioning system, such as a GPS system for determining the position of a vehicle. The positioning system communicates with the operating system. An information database, communicating with the operating system, contains data related to routing information concerning routes for travel by the vehicle. The routing information includes safety information concerning route safety in the traveling region accessible by the vehicle. The apparatus further includes a routing system in communication with the operating system that determines a route based at least in part on the routing information. Driving directions and call information are provided multi-modally to provide the officer with critical information in an efficient and timely fashion.

An integrated circuit including two phase-locked loops each with its own oscillator. To prevent locking owing to injection between the two oscillators due to stray currents in the integrated circuit, a noise generator is coupled to the oscillator of one of the loops and a timer is provided for activating the noise generator in a manner such that the noise generated changes the frequency of the oscillator randomly when the other loop is in operation.
摘要:
Generator of clock pulses having a period selectable between a first period, a second period of greater duration than that of the first period and a third period, with duration imposed by the transitions of a synchronization signal (SYNC) from a first to a second logic level, comprising: a resettable oscillator controlled by a binary selection signal having a first and second logic level, in order to generate periodic pulses having the first or second period depending on the logic level of the said selection signal, the oscillator comprising a pulse extractor triggered by the periodic pulses and by the transitions from first to second logic level of the synchronization signal in order to generate, with each pulse and transition received as input, one of the said periodic clock pulses, acting as reset signal for the oscillator, and a finite state logic machine, having at least two states A, B and inputs for receiving the synchronization signal and the periodic pulses, and generating the selection signal at a first logic level, in state A, and at the second logic level in state B, the machine evolving from state to state as a function of the signals and received as input.
摘要:
A method and system for differentiating between intended user input and inadvertent or incidental contact with a touchpad is herein disclosed. When a user engages the touchpad, sensors on the touchpad are activated and generate touch sensor signals. Based on the pattern of engaged sensors, a hand pattern can be determined. From the hand pattern, a hand model may be retrieved. The hand model may indicate passive zones and active zones. Contact in the active zones may be considered intentional, while contact in the passive zones may be considered unintended or incidental. Moreover, a global shift may be calculated, and input from the active zones may be compensated for the global shift. The input from the active zones can then be used to control a graphical user interface.

The pointer management technology establishes a protocol and method for dual pointer management in both absolute input mode and relative input mode. The method defines a set of properties/constraints for contextual dynamic remapping between input sensor coordinates and target screen coordinates. The remapping of the left pointer (respectively the right pointer) depends on the position of the right pointer (respectively the left pointer) in the target screen space. This inter-dependence enables a more flexible and more powerful interaction as it exploits the contextual layout to re-estimate the remapping transformations at each instant.

Sensors around the periphery of the remote control unit detect contact with the user's hand. A trained model-based pattern classification system analyzes the periphery sensor data and makes a probabilistic prediction of the user's hand size. The hand size is then used to control a mapping system that defines how gestures by the user's thumb upon a touchpad of the remote control unit are mapped to the control region upon a separate display screen.
摘要:
The hand held case of the remote control unit includes at least one touchpad, and other sensors, such as acceleration sensors, case perimeter sensors, pressure sensors, RF signal sensors. These sensors provide a rich array of sensory inputs that are classified by a pattern recognizer to generate control commands for both the consumer electronic equipment and the remote control unit itself. A power management system to conserve unit battery power is also responsive to the pattern recognizer to allow intelligent power management control. The control system uses the display of the consumer electronic equipment to provide instructions to the user, and the behavior of the remote control system uses what is displayed on the display as context information for pattern recognition.
