A power supply circuit for providing power and detecting a plurality of loads' input voltages on a motherboard includes a pulse width modulation (PWM) controller, a voltage output circuit and a voltage feedback circuit electrically connected to the PWM controller and the plurality of loads. The PWM controller outputs PWM control signals. The voltage output circuit receives the PWM control signals and outputs working voltage to the plurality of loads according to the received PWM control signals. The voltage feedback circuit detects the plurality of loads' input voltages and outputs feedback signals to the PWM controller according to the detected input voltages. The PWM controller adjusts its PWM control signal outputs, according to the received feedback signals, and adjusting working voltages to the plurality of loads.

A computer-aided design (CAD) system may support detection of internal channel networks for 3D printing and may include a CAD model access engine and a channel network detection engine. The CAD model access engine may access a CAD model of a physical object to be constructed through 3D printing. The channel network detection engine may detect an internal channel network included in the CAD model of the physical object, including by identifying channel openings along a surface of the CAD model that satisfy an opening size threshold and recursively identifying internal faces of the CAD model that form the internal channel network, wherein the internal faces are faces of the CAD model that are internal to the surface of the CAD model. The channel network detection engine may also perform a channel verification on the identified internal channel network to support the 3D printing of the physical object.

A joint structure includes a first connecting unit, a second connecting unit, and a securing member. The first connecting unit has a distal end portion, a proximate end portion, and a connecting surface formed on the proximate end portion. The second connecting unit has a coupling surface and a connecting slot formed on the coupling surface. The securing member is configured to securely connect the first and second connecting units, so when the proximate end portion of the first connecting unit is inserted into the connecting slot of the second connecting unit, the securing member is configured to lock up the first and second connecting units. The joint structure is configured to prevent lateral rotational movement between the first and second connecting units and to reinforce the furniture structure having such joint structure, especially when an excessive load is applied to the distal end of the connecting unit.
摘要:
Sensors provisioned on a first device detect a movement of the first device corresponding to the first device changing position within an environment. Location information for the first device is updated based on the position change. A plurality of signals are detected, at the first device, from a second device in the environment, determine, and a distance between the first and second devices is determined based on each of the signals. From the signals, another change in position of the first device within the environment is determined and the location information updated for the first device. The movement is detected at the first device at an instance between two of the plurality of signals, and location information for the first device based on the first position change is updated prior to detection of the later of the two signals in the plurality of signals.

A bed set includes a bed frame which includes a headboard, and a footboard bench, wherein the footboard bench includes a base frame and a back frame upwardly extended from the base frame. The back frame of the footboard bench serves as a footboard of the bed frame to match with the headboard of the bed frame. In particular, an ornamental design of the back frame of the footboard bench matches with an ornamental design of the headboard of the bed frame, so as to enhance an aesthetic appearance of the bed set.
