Abstract: Disclosed are an unblocking apparatus for a furnace discharging pipe and a use method. The unblocking apparatus includes a rail, a rail car that may move along the rail, an unblocking drive mechanism arranged on the rail car, a heat-unblocking component, a cold-unblocking component, and a material receiving component that is used to receive a blocking material in the discharging pipe, and a drive end of the unblocking drive mechanism is detachably connected with one end of the heat-unblocking component and the cold-unblocking component respectively. The present application effectively handles different blockage situations of the furnace discharging pipe by connecting the unblocking drive mechanism with an unblocking rod capable of heat-unblocking and a drilling rod capable of cold-unblocking, thereby two modes of heat-unblocking and cold-unblocking are performed on the furnace discharging pipe; and the discharging pipe may be unblocked by a remote operation.

Abstract: A discharge unit is connected to a power pad, a ground pad, and an I/O pad, and can discharge an electrostatic charge when an electrostatic pulse appears on any of the power pad, the ground pad, and the I/O pad. The discharge unit includes a first discharge unit and a second discharge unit, the first discharge unit is connected to the second discharge unit, the power pad, and the I/O pad, and the second discharge unit is connected to the ground pad and the I/O pad. The first discharge unit and/or the second discharge unit can discharge electrostatic charges on different pads, respectively.

Abstract: A method for estimating the pressure measurement bias of a barometric sensor in a wireless terminal. A location engine using the method generates an enhanced estimate of the measurement bias. The location engine generates the enhanced estimate based in part on Global Navigation Satellite System (GNSS)-based estimates of the elevation of the wireless terminal, which the terminal generates as it concurrently makes barometric pressure measurements. Each GNSS-based estimate of elevation is often generated from noisy measurements and has an associated uncertainty. The location engine accounts for the uncertainty in the GNSS estimates of elevation by applying an optimal estimation technique, such as Kalman filtering, on the biased pressure measurements and the GNSS-based estimates.

Abstract: A system for intra-operatively registering a pelvis comprising an acetabulum with a computer model of the pelvis in a coordinate system. The system may include: a) a surgical navigation system including a tracking device; and b) at least one computing device in communication with the surgical navigation system.
