Abstract: The present disclosure generally relates to sharing workout content on electronic devices.

Abstract: In some examples, an electronic device includes a printed circuit board (PCB) device that includes a first trace electrically connected to a first pad of a first trace via on a first layer and a second trace electrically connected to a second pad of a second trace via on a second layer. In some examples, the PCB device also includes four ground pads on the first layer and an antipad surrounding the two trace vias, where a first ground pad is positioned between the first trace and the second trace, where the first ground pad and the second ground pad are approximately symmetrically positioned about a perpendicular bisector of a line from the first pad to the second pad, and wherein the third ground pad and the fourth ground pad are approximately symmetrically positioned about the perpendicular bisector of the line from the first pad to the second pad.

Abstract: A frequency synthesizer and a method for constructing the same by using the architecture of digital process frequency loop (DPFL) are disclosed. The DPFL frequency synthesizer with the DPFL architecture includes a reference frequency divider counter, an output divider counter, a processor, a memory, a digital to analog converter (DAC), and a voltage Control Oscillator (VCO). The method uses the processor to perform the signal processing to correct the output frequency of the VCO in the frequency domain. The memory stores the nonlinear characteristics of the VCO such that the synthesizer is completely controlled, no uncertain frequency being captured during process, and the frequency resolution of the synthesizer is programmable.

Abstract: An improved Automatic Test Equipment (ATE) in which Instruction Memory and a Vector Memory are combined together into a tester pattern memory in order to share the same memory space. As such, reducing the memory, size, and cost of the Automatic Test Equipment.
