A target detecting device includes: an optical scanner including a mirror; and a casing. The target detecting device further includes a light shielding portion configured to partition the casing into a light projecting space through which projected light travels and a light receiving space through which reflected light travels and configured to block light. The mirror has a first reflecting region which reflects the projected light and a second reflecting region which reflects the reflected light, the first reflecting region and the second reflecting region being located in an identical reflecting surface. The light shielding portion includes: a movable light shielding portion provided on the mirror so as to separate the first reflecting region and the second reflecting region and configured to be movable in conjunction with the mirror; and a fixed light shielding portion fixed to the casing so as to surround the movable light shielding portion.

This invention provides a semiconductor device contrived to prevent a reference voltage and a reference current which are supplied to a high speed OCO from varying with a change in ambient temperature and/or a change in an external power supply voltage and to reduce the circuit area of a power supply module. The high speed OCO outputs a high speed clock whose magnitude is determined by the reference current and the reference voltage. A temperature sensor detects the ambient temperature of the high speed OCO and a voltage sensor detects the operating voltage of the high speed OCO. The power supply module includes a BGR and generates the reference voltage, reference current, and operating voltage of the high speed OCO, based on a primary reference voltage which is output by the BGR. A flash memory stores a table specifying trimming codes for the reference voltage and reference current, related to an ambient temperature and an operating voltage of the high speed OCO. A logic unit adjusts the values of the reference current and reference voltage, according to the reference voltage and reference current trimming codes related to the detected ambient temperature and operating voltage.

An object detection device includes: a light emitter; a light receiver; a rotating scanner having a mirror and reflecting light from the light emitter off the mirror by rotating the mirror to scan the reflected light over a predetermined range, and reflecting light reflected off a target off the mirror to guide the reflected light to the light receiver; an object detector detecting whether there is a target, based on a light reception signal; a light guider guiding light from the light emitter to the light receiver; and a failure detector detecting whether there is a failure, based on a light emission state of the light emitter and a light reception state by the light receiver. The light guider receives light emitted from the light emitter and reflected off the mirror, and reflects the light off the mirror to guide the reflected light to the light receiver.
摘要:
A laser radar system is installed in a moving body and includes a plurality of scanning type laser radar devices which detect distances to an object. The scanning type laser radar device has a first direction and a second direction in a scanning range. In the first direction, a detectable distance to an object having identical reflectance is longer. In the second direction, a detectable distance to an object having identical reflectance is shorter. The scanning range of one scanning type laser radar device overlaps with the scanning range of another scanning type laser radar device adjacent to the one scanning type laser radar device such that the detectable area in the first direction of the one scanning type laser radar device overlaps with the detectable area in the second direction of the other scanning type laser radar device.

A semiconductor flash memory includes an erase/write control unit that, when performing an erase/write operation of read memory cells, reads and senses memory current of the read memory cells for each memory cell, and adjusts threshold voltage of each of the read memory cells to a predetermined value, and a readout control unit that, when performing a read operation, selects at least two read memory cells simultaneously from among the read memory cells to which the erase/write control unit stored the same data, and senses total memory current for the at least two read memory cells.
