Abstract: Examples may include techniques for using a sample clock to measure a duty cycle by periodic sampling a target clock signal based on a prime number ratio of a reference clock frequency. The reference clock frequency used to set a measurement cycle time over which the duty cycle is to be measured. A magnitude of a duty cycle error as compared to a programmable target duty cycle is determined based on the measured duty cycle and the duty cycle is adjusted based, at least in part, on the magnitude of the duty cycle error.

Abstract: Forming an integrated circuit, for example by first, concurrently forming a first front end of line (FEOL) layer having a first thickness and a surface contacting or facing a semiconductor substrate frontside and a second FEOL layer, having a second thickness and including a same material as the first FEOL layer and having a surface contacting or facing a semiconductor substrate backside, and second, processing the second FEOL layer to reduce the second thickness.

Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

Abstract: An autonomous surface cleaning apparatus includes a body, a drive system carried by the body and configured to move the autonomous surface cleaning apparatus across a surface, a cleaning assembly disposed at a front of the body and projecting forward beyond a front surface of the body, the cleaning assembly having a generally planar front surface and first and second side surfaces that extend rearward from opposite ends of the front surface. The apparatus further includes a first forward proximity sensor disposed at the front surface of the cleaning assembly adjacent to a first front corner of the cleaning assembly and a second forward proximity sensor disposed at the front surface of the cleaning assembly adjacent to a second front corner of the cleaning assembly. The first and second forward proximity sensors are angled inwardly towards a longitudinal axis of the cleaning assembly.

Abstract: An electronic device may be provided with peripheral conductive housing structures, a first antenna, and a second antenna. A gap may divide the housing structures into a first segment forming an arm of the first antenna and a second segment forming an arm of the second antenna. A first feed terminal may be coupled to the first segment and a second feed terminal may be coupled to the second segment. Switchable components may be coupled in parallel between the first and second feed terminals across the gap. The switchable components may be adjusted to tune the frequency response of the first and/or second antenna. The switchable components may have a first state in which only the first feed terminal feeds the first antenna and may have a second state in which both the first and second feed terminals feed the first antenna.

Abstract: A method (1200) by a wireless device (110) operable to perform receive beam sweeping over a set of a plurality of receive beams includes receiving (1202), from a network node, assistance information. The wireless device determines (1204), based on the assistance information, a first subset of receive beams within the set of the plurality of receive beams. The wireless device performs (1206) at least one operation based on the first subset of receive beams.
