摘要:
A railroad track inspection system and method for facilitating inspection of a rail component while traveling on the railroad track. The railroad track inspection system includes an optical path protection device for a protective window for optical sensors of an optical inspection system when it becomes contaminated with dirt, dust, mud, grease, and other contaminants that block or obscure an optical path of the sensors. The optical path protection device eliminates the need for a human operator to perform the periodic cleaning of the protective window by using a clear film with an automated advancement mechanism for providing clean film, as needed, for keeping the optical path of the optical sensors unobstructed and clear.

A dosimeter that is configured to assist with patient-specific quality assurance (“QA”) in arc-based radiotherapy, such as stereotactic radiotherapy, is provided. The dosimeter facilitates acquiring multiple different dosimetric measurements simultaneously. For instance, the dosimeter can be configured to acquire dosimetric measurements from multiple different modalities, including gel dosimetry and film dosimetry, and is configured for simultaneous use with a diode-array QA phantom.

A peripheral device and a method for operating a peripheral device is disclosed. The peripheral device includes one or more connection mechanisms for coupling to a computing device, a power supply, and a controller. The controller is configured to enable the peripheral device to communicate with the computing device. When the peripheral device is coupled to the computing device, the controller is configured to determine the amount of power remaining in the power supply of the peripheral device, and based at least in part on the amount of power remaining in the power supply of the peripheral device, enable the peripheral device to charge a power supply of the computing device, and enable the peripheral device to receive power from the power supply of the computing device.

A method and system for enhancing the life of a battery within a portable or otherwise battery operated electronic device. The method and system provide selectable display modes, e.g., from color to monochrome, that can be changed in order to enhance the life of the device's battery. The monochrome display mode can be selected by the when the battery level is detected below a predefined threshold. In one embodiment, the electronic device is a hand held computer system with a display device. When the battery level is detected as below a preselected level, a message may be generated on the computer display screen. The display mode can change from color to monochrome thereby saving power because the monochrome display. In one embodiment, color sequential techniques are used to provide a flat panel color display. Within the display, a transreflective layer provides reflective light for monochrome applications. When the battery energy returns to normal levels, the color display mode can be re-entered automatically. It is appreciated that the display mode changes can also be performed automatically if the battery level falls below certain critical levels.

A method and apparatus that allows for controlling operating time of a portable computer system and a peripheral device. A portable computing system that includes a rechargeable power supply and that includes a connection mechanism for coupling to a peripheral device is used to control operating time of the portable computer system and the peripheral device. In one embodiment, a user can choose between maximizing the operating time of the portable computer, maximizing the operating time of the peripheral device, or maximizing the life of the entire system (maximizing the operating time of the portable computer system and the peripheral device). When operating time of the portable computer system is to be maximized, power is sent from the peripheral device to the portable computer system to extend the operating time of the portable computer system. Similarly, when operating time of the peripheral device is to be maximized, power is sent from the rechargeable power supply of the portable computer system to the peripheral device to extend the operating time of the peripheral device. When operating time of the entire system is to be maximized, power is moved such that the operating time for the portable computer system is equal to the operating time of the peripheral device.

A method and system for enhancing the life of a battery within a portable or otherwise battery operated electronic device. The method and system provide user selectable display modes, e.g., from color to monochrome, that can be changed in order to enhance the life of the device's battery. The monochrome display mode can be selected by the user when the battery level is detected below a predefined threshold. In one embodiment, the electronic device is a hand held computer system with a display device. When the battery level is detected as below a preselected level, a message is generated on the computer display screen. The message informs the user that the display mode of the screen can be changed to enhance the battery life. If selected, the display mode can change from color to monochrome thereby saving power because the monochrome display does not utilize a back-lighting element. In one embodiment, color sequential techniques are used to provide a flat panel color display. Within the display, a transreflective layer provides reflective light for monochrome applications. When the battery energy returns to normal levels, the color display mode can be re-entered automatically. It is appreciated that the display mode changes can also be performed automatically if the battery level falls below certain critical levels.
摘要:
A miniature keyboard wherein the keys are arranged in a way to improve data entry and decrease the chance of depressing multiple keys at a time. Accordingly, the height of the keys are patterned to decrease the chance of multiple key depressions thus increasing the accuracy of data input into the personal digital assistant. In one embodiment, the height of the keys is alternated down the individual rows of keys. In another embodiment, the height of the keys is alternated across individual columns of keys. Similarly, in another embodiment, the heights of the keys are arranged in a checkered pattern on the keyboard. In addition, another embodiment staggers the heights of the keys and incorporates embodiments mentioned above. By incorporating different key arrangements and alternating the height of the keys, key differentiation, key navigation, and data input accuracy is greatly improved due to the improved tactile feedback provided by the miniature keyboard.
