Abstract: An optoelectronic computing system includes a first semiconductor die having a photonic integrated circuit (PIC) and a second semiconductor die having an electronic integrated circuit (EIC). The PIC includes optical waveguides, in which input values are encoded on respective optical signals carried by the optical waveguides. The PIC includes an optical copying distribution network having optical splitters. The PIC includes an array of optoelectronic circuitry sections, each receiving an optical wave from one of the output ports of the optical copying distribution network, and each optoelectronic circuitry section includes: at least one photodetector detecting at least one optical wave from the optoelectronic operation. The EIC includes electrical input ports receiving respective electrical values.

Abstract: An electronic device may be provided with peripheral conductive housing structures having a segment that forms a resonating element for an antenna. A speaker may be mounted to a mid-chassis of the electronic device. A printed circuit may be mounted to the speaker and may have a ground trace for the antenna. A conductive spring may extend through the printed circuit and the speaker to couple the ground trace to the mid-chassis. A conductive contact pad may be welded to an aluminum layer such as an aluminum layer used to form the mid-chassis. A conductive spring such as the conductive spring coupled to the ground traces may press against the contact pad. The contact pad may include gold or nickel-plated stainless steel. The contact pad may provide a strong electrical connection between the conductive spring and the aluminum layer.

Abstract: An electronic device may be provided with a liquid crystal polymer (LCP) printed circuit having conductive trace and a hole. A conductive flange may be soldered to the conductive trace and may extend into the hole. The end of the conductive flange may laterally surround a central opening within the hole. A conductive contact may be inserted into the central opening. Solder may be deposited over the conductive flange and in the central opening. The solder may couple the conductive contact to the conductive flange and thus the conductive trace. This may ensure a robust mechanical and electrical connection between the conductive contact and the conductive trace on the printed circuit despite the printed circuit being formed from LCP, which may not support copper-plated through vias for coupling to the conductive contact.

Abstract: The present disclosure relates to a dirty paper coding (DPC) scheme for a wireless communication system. One example encoding device obtains symbol probabilities for symbols of a symbol sequence given an effective interference based on a target distribution of symbols of a transmit signal, encodes a message into the symbol sequence based on the symbol probabilities, and then obtains the transmit signal based on a mapping of the symbol sequence and the effective interference using a scalar function. One example decoding device obtains a receive signal, obtains a symbol sequence based on the receive signal and a scaling factor using a scalar function, and then decodes the symbol sequence to obtain a message.
