A method includes: training a machine learning model with a plurality of electronic circuit placement layouts; predicting, by the machine learning model, fix rates of design rule check (DRC) violations of a new electronic circuit placement layout; identifying hard-to-fix (HTF) DRC violations among the DRC violations based on the fix rates of the DRC violations of the new electronic circuit placement layout; and fixing, by an engineering change order (ECO) tool, the DRC violations.

Adaptive tunable antennas for wireless devices

Fechniques for adjusting one or more antenna parameters to optimize the performance of a wireless device are disclosed. In an embodiment, a variable antenna match is provided with a control signal for selecting a preferred antenna match setting. The preferred antenna match setting may correspond to the setting having a best signal quality metric. In a further embodiment, a variable antenna electrical length module is provided with a control signal for selecting a preferred antenna electrical length. Further techniques for accommodating multiple antennas are disclosed.

Radar detection algorithm

A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.

Tool box which is assembled by a part which is composed of two boards folded in a form of an L-shaped part

A tool box comprises a first part (10) composed of two boards (12,13) foldably connected with each other in the form of an L-shaped part and a second part (20) including three boards (22-24) foldably connected with each other and in the form of a U-shaped member. At each foldable connection, each board (12,13,22-24) has an inclined surface, such surfaces being held in engagement on folding the boards by interengaging projections and recesses. The second part (20) is mounted to the first part (10) by engaging projections (122) on the first part (10) with recesses (243) in the second part so as to form a tool box with an opening defined in a front side. Drawers (30) slidably engage with rails (225) inside the box and a handle connection is provided in the uppermost board (23).

Circulating element for ball screw and ball screw using the circulating element

A circulating element for ball screw includes a first surface defining a circulating passage that extends from one lateral side of the first surface to the other lateral side of the first surface and has a coupling mouth located on each of the two opposite ends thereof, and a second surface defining a coupling groove between the two coupling mouths of the circulating passage and two guide blocks respectively protruding out of the coupling mouths of the circulating passage. Thus, the circulating element has the advantages of low processing cost, ease of installation, high alignment accuracy, and excellent running smoothness.
