A woodworking machine includes a base, an adjusting device, and an adjustable worktable. The adjusting device is engaged with the base and includes a platform, a plurality of adjusters, and a plurality of fastening members. The platform is slidably engaged with the base. The plurality of adjusters are adjustable, and the plurality of fastening members are releasably inserted through the plurality of adjustors respectively. The adjustable worktable is engaged with the adjusting device. Moreover, the platform bears the adjustable worktable and the plurality of adjusters are abutted against the adjustable worktable. Additionally, the adjustable worktable is adjustably moved upon adjusting of the adjustors, and prior to adjusting each adjustor, the fastening member engaged therewith is removed.

A system for automatically sharing virtual objects between different mixed reality environments is described. In some embodiments, a see-through head-mounted display device (HMD) automatically determines a privacy setting associated with another HMD by inferring a particular social relationship with a person associated with the other HMD (e.g., inferring that the person is a friend or acquaintance). The particular social relationship may be inferred by considering the distance to the person associated with the other HMD, the type of environment (e.g., at home or work), and particular physical interactions involving the person (e.g., handshakes or hugs). The HMD may subsequently transmit one or more virtual objects associated with the privacy setting to the other HMD. The HMD may also receive and display one or more other virtual objects from the other HMD based on the privacy setting.

A worktable includes a protective member designed therefor. The worktable includes a platform, and at least one extended platform connected thereto. The protective member includes a frame and a base connected on a bottom edge of the frame. The base including a first base section on which the platform is supported and at least one second base section on which the at least one extended platform is supported. The frame includes a periphery enclosing the platform and the at least one extended platform so as to prevent them from being damaged.

摘要:
An interrogation circuit can inductively couple to a sensor and measure the change in fundamental frequency. The change can be used to measure the environmental factor. Sensor sensitivity and inductive coupling efficiency can be competing design constraints. A driver, electrically connected to the sensor and inductively coupled to the interrogation circuit, can relax the constraints. The driver, however, can introduce noise into the sensor. The sensor can be shielded using physical and geometric techniques to reduce the noise.
摘要:
An acoustic wave device and related systems and methods, with some embodiments comprising a device with both an acoustic wave sensor and a SAW RFID. In some embodiments, the device is powered by capturing energy from the surrounding environment without the need for an interrogating RF signal.

An acoustic wave particulate sensor system is disclosed, which includes a piezoelectric substrate; and one or more acoustic wave sensing elements formed upon said piezoelectric substrate. A housing can be provided for maintaining said piezoelectric substrate and the acoustic wave sensing elements, wherein the acoustic wave sensing elements, when exposed to a substance containing particulates, such as, for example, engine oil, responds to a phase change, frequency change, and/or noise level change associated with said particulates in order to identify a noise signature of said particulates and therefore identify differences among said particulates to detect data associated with said particulates.
