摘要： A Micro Inertial Measurement Unit (IMU) which is based on MEMS accelerometers and gyro sensors is developed for real-time recognition of human hand motions, especially as used in the context of writing on a surface. Motion is recorded by a rate gyro and an accellerometer and communicated to a Bluetooth module, possibly to a computer which may be 20 to 30 feet or more from the sensor. The motion information generated and communicated is combined with appropriate filtering and transformation algorithms to facilitate a complete Digital Writing System that can be used to record handwriting on any surface, or on no surface at all. The overall size of an IMU can be less than 26 mm×20 mm×20 mm, and may include micro sensors, a processor, and wireless interface components. The Kalman filtering algorithm is preferably used to filter the noise of sensors to allow successful transformance of hand motions into recognizable and recordable English characters. The immediate advantage is the facilitation of a digital interface with both PC and mobile computing devices and perhaps to enable wireless sensing.

摘要： A small hand-held tubular shaped flashlight utilizes a liquid to absorb heat energy from a high intensity light source such as an LED base member such as a heat sink, capsule or other light source, and assists in absorbance and transport of heat energy. The liquid preferably transfers the heat throughout the long cylindrical handle, and utilizes the surface area of the long flashlight body for even heat rejection without localized hot spots. In the alternative, a liquid can store the heat through melting/crystallization, where the liquid takes the form of a solid with low melting point (such as a wax) that melts during use but re-solidifies or crystallizes during periods of non-use. The use of a liquid jacket around these batteries also makes the flashlight attractive for low temperature service where the heat from the LED can be used to warm the batteries.
摘要翻译：小型手持式管状手电筒利用液体吸收来自诸如散热器，胶囊或其他光源的LED底座等高强度光源的热能，并有助于吸收和传输热能。液体优选在整个长圆柱形手柄中传递热量，并且利用长手电筒体的表面积进行均匀排热而不局限于热点。在另一种方案中，液体可以通过熔化/结晶储存热量，其中液体采用低熔点固体（如蜡）的形式，其在使用期间熔化，但在不使用期间再凝固或结晶。在这些电池周围使用液体护套也使得手电筒对于低温服务是有吸引力的，其中可以使用来自LED的热量来加热电池。
