A method and apparatus for measuring an electromagnetic field are disclosed. In accordance with the apparatus an array of substantially identical antenna elements having a substantially shorter length than a wavelength of the electromagnetic field and being equi-spaced are provided. The spacing is larger than approximately three times the length of the antenna elements. Each antenna element is for sensing the electromagnetic field at a predetermined location and for providing a signal in dependence upon the sensed field. By providing antenna elements meeting the criteria set out herein accurate electromagnetic field strengths are measurable absent significant mutual coupling and scattering effects between the antenna elements.

A removable modular duct system for conducting air in a temperature-controlled cargo container. Temperature-controlled air produced and propelled by a refrigeration unit, is conducted along the modular duct system by one or more duct sections and a transition section that conducts air from the refrigeration unit to the duct sections. The air may be discharged laterally via lateral discharge openings in the duct sections. An end section may be coupled to the duct sections to discharge air at the end of the duct system.

A method and system for the automated detection of lesions such as masses and/or tissue (parenchymal) distortions in medical images such as mammograms. Dense regions and subcutaneous fat regions within a mammogram are segmented. A background correction may be performed within the dense regions. Hough spectrum within ROIs placed in the breast region of a mammogram are calculated and thresholded using the intensity value .eta. in order to increase sensitivity and reduce the number of false-positive detections. Lesions are detected based on the thresholded Hough spectra. The thresholded Hough spectra are also used to differentiate between benign and malignant masses.

An LED illumination system is operable to irradiate plant materials with photosynthetically active radiation. A lighting assembly includes a plurality of different LED types. Each LED lamp has a different spectral power matched to an absorption peak of the plant materials. All of the LED lamps of each different lamp type are driven by a different dedicated power source. Each power source can be independently modulated to vary the collective spectral power output of the LED illumination system. The lighting assembly includes fluid conduits disposed proximate to the LED lamps and a cooling fluid is flowed through the fluid conduits to removed thermal energy from the LED lamps.

A helmet with a sports camera comprises a body and a picture recording module which is detachably mounted on the body. The picture recording module includes an outer shell and a camera disposed in the outer shell. The camera is electrically connected to a control system; the control system is connected to a power module; the control system is further electrically connected to an LED indicator and an operating button; in use, through controlling the operating button, a user can take photos or record a video. Advantages of the helmet with a sports camera are summarized as follows. 1. The helmet and the camera are integrated, which facilitates the photographing of sceneries. 2. LED indicators and operation buttons on the helmet can control the start-up, shooting, or recording of the camera, and the micoUSB data interface can be used for charging, data copying, or connected to a PC camera. 3. An external vehicle-mounted display can be provided, which operates to real-time show the shot pictures or sceneries for users to browse through wireless communication technology.
摘要:
The disclosure relates to a bone conduction-based Bluetooth wireless riding helmet comprising a helmet body, a regulator at an interior of the helmet body, a brim at a front end of the helmet body, and a drawstring connecting two sides of a bottom of the helmet and the drawstring is fixed on the helmet through a quick release buckle; wherein an interior of the helmet body is provided with a removable bone conductor that is electrically connected with a power system and a control system; wherein the control system is electrically connected with a regulating device on the drawstring. The disclosure has the following beneficial effects. On the bone conduction-based helmet, a bone conduction-based vibrator sound source is embedded on each side of the helmet and perfectly integrated with the helmet, so that sounds can be clearly heard even when both ears of a rider are covered and even when it is used in a noisy environment.
摘要:
Methods and apparatus relating to disabling one or more cache portions during low voltage operations are described. In some embodiments, one or more extra bits may be used for a portion of a cache that indicate whether the portion of the cache is capable at operating at or below Vccmin levels. Other embodiments are also described and claimed.
摘要:
Disclosed is a dual wafer stage switching system for a lithography machine. The system comprises a base stage (30), a wafer stage (16.1) running at a pre-processing workstation, and a wafer stage (16.2) running at an exposure workstation. A rotating motor (41) is mounted under the base stage (30) for rotating the two wafer stages after the wafer stages have completed pre-processing and exposure operations in order to complete position switch of the wafer stages, wherein the base stage (30) is kept stationary during the switch. The present invention avoids rotation of a large inertia base stage and has low requirement for motor power, while eliminating a guide rail docking device and an auxiliary device and greatly simplifying system configuration. The system is easy and convenient to operate and easy to control.
