摘要:
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 spinal screw assembly is provided. The assembly may be provided with a screw and a movable head in which angulation of the screw relative to the movable head is constrained so that angulation within limits is allowed in one plane but lesser or no angulation is allowed in another plane. Methods to assemble the disclosed apparatus are also disclosed.

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.
摘要:
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.

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.
摘要:
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.
摘要:
A helper SDK embedded in a native application performs local operations on behalf of a web application affiliated with the helper SDK. The helper SDK may perform security functions such as fingerprint or face biometric verifications as well as access device-specific hardware such as a camera or secure memory. The web application may use an 0Auth technique for access and refresh tokens. In a transaction system, when a user is confirmed via the security function, order details are passed to the web application with a refresh token and ciphertext confirmation data is returned to the native application for completion of the transaction.
