A base apparatus for providing engagement to advice holder is provided, including a connection unit, a fixed unit, and at least a weight unit. The connection unit is for connecting a clapper or holder of electronic device, and the fixed unit is engaged to the bottom of the connection unit. The weight unit is sandwiched between and partially contained within the boundaries of the connection unit and the fixed unit. The weight unit includes a wrap means, an anti-slip means, and at least a weight object. The boundaries of the anti-slip means and the wrap means are engaged together to form a space for accommodating the weight object.

An inter-carrier interface removal device can improve estimation accuracy of inter-carrier interference caused by Doppler shift in a received multi-carrier signal moving at a high speed, and a reception characteristic of the multi-carrier signal after removing the inter-carrier interference. The inter-carrier interference removal device includes: a channel estimation unit (101) estimating a channel frequency characteristic according to a carrier signal; an equalization unit (102) equalizing the carrier signal with the channel frequency characteristic and outputs tentative carrier data; a reliability value calculation unit (103) calculating a reliability value according to the channel frequency characteristic; a weighting unit (104) weighting the tentative carrier data with the reliability value; and an ICI component estimation unit (106) estimating an ICI component according to the weighted tentative carrier data and the estimated channel frequency characteristic; and an ICI removal calculation unit (107) removing the ICI component from the carrier signal.

The invention relates to vehicle used high-temperature lead acid battery negative pole lead plaster and a preparation method thereof, belongs to the storage battery technical field and is used for improving the high-temperature service life and the low-temperature starting capacity of the storage battery. The technical proposal is as follows: the lead plaster solid raw material comprises the following materials by the weight unit: 100 units of lead powder, 0.01 to 0.5 units of sodium lignosulfonate, 0.01 to 0.8 units of high-temperature sodium lignosulfonate, 0.01 to 1.0 unit of graphite powder, 0.03 to 0.08 units of fibre, 0.3 to 1.2 units of barium sulfate, 0.2 to 1.0 units of humic acid and 0.1 to 0.4 units of black carbon. The materials, such as the high-temperature sodium lignosulfonate and the graphite powder are added to the compounding recipe of the negative pole lead plaster, thereby the performance of the negative pole active materials is effectively improved at the high temperature by matching with the reasonable compounding recipe ratios of the added materials, the contraction is reduced, thereby the high-temperature service life and the low-temperature starting capacity of the storage battery are enhanced, particularly the high-temperature service life can be above 90 percent higher than the storage battery prepared based on a common compounding recipe.

A target recognition system and a target recognition method to recognize one or more recognition targets, operatively connected to an imaging device to capture an image of an area ahead of the target recognition system, each of which includes a recognition area detector to detect multiple recognition areas from the captured image; a recognition weighting unit to set recognition weight indicating existence probability of images of the recognition targets to the respective recognition areas detected by the recognition area detector; and a target recognition processor to recognize the one or more recognition targets in a specified recognition area based on the recognition weight set in the respective recognition area.

A light input-adjustable window shade includes a supporting unit having a main rod and two sliding rods. Each sliding rod is slideably mounted to one of two ends of the main rod. A positioning seat is fixed to an end of each sliding rod distant to the main rod. Each sliding rod has a coupling portion. A spool is rotatably mounted to the positioning seats of the supporting unit. A shade body includes a first periphery fixed to the spool and a second periphery. The shade body is coiled around the spool. A weighting unit includes a rod body comprised of an inner rod and two movable rods. Each movable rod is slideably mounted to one of two ends of the inner rod. The shade body is wound around the rod body. The second periphery of the shade body is fixed to the coupling portions of the two sliding rods.
