An signal switching integrated-circuit die includes an array of switch cells, control signal contacts, data input contacts and data output contacts. Switch control signals are received from an external control-signal source via respective control signal contacts, inbound data signals are received from one or more external data-signal sources via respective data input contacts and outbound data signals are conveyed to one or more external data-signal destinations via respective data output contacts. The array of switch cells receives the control signals directly from the control signal contacts and response to the control signals by switchably interconnecting the data input contacts with selected ones of the data output contacts.

A touch sensor is provided which includes one or more liquid metal wires and detection circuitry to detect a change in an electrical attribute of the one or more liquid metal cavities based on a depression of the one or more liquid metal cavities, and indicate a touch event corresponding to the depression of the one or more liquid metal cavities based on the change in the electrical attribute.

An integrated circuits with sequential logic circuitry is provided. The sequential logic circuitry may including latching circuits that receive clock signals from on-chip or off-chip clock sources. The clock signals may exhibit clock skew that is native to the integrated circuit. The natively existing clock skew can be leverage to perform time borrowing to help optimize circuit performance. The desired clock skew can be achieved by intelligent placement of the clock sources and deliberate routing of the clock signals from the clock sources to respective types of clock distribution networks on the integrated circuit.

Presented are manufacturing control systems for fabricating composite-material structures, methods for making/operating such systems, and resin transfer molding techniques for ameliorating race-tracking effects in fiber-reinforced polymer panels. A method for forming a composite-material construction includes confirming, via a system electronic control unit (ECU), that a fiber-based preform is placed in a mold cavity and that opposing mold segments of the molding apparatus are sealed together. A filler, such as a compressible bladder, a cluster of spring-biased pins, or a spray-chopped fiber bed, is introduced into a void between the fiber-based preform and a tool face of one mold segment to thereby eliminate an unwanted resin race track. The system ECU commands a resin pump to inject resin through a primary gate of the molding apparatus and into the mold cavity to thereby impregnate the fiber-based preform with the resin. One or more vents operate to evacuate air from the mold.
