  • Patent number: 11972062
    Abstract: A keyboard may be provided that has keys overlapped by a touch sensor. The keyboard may have key sensor circuitry for monitoring switching in the keys for key press input. The keyboard may also have touch sensor circuitry such as capacitive touch sensor circuitry that monitors capacitive electrodes in the touch sensor for touch sensor input such as multitouch gesture input. The keyboard may include an outer layer of fabric that overlaps the keys. The fabric may have openings that are arranged to form alphanumeric characters. Light sources may emit light that passes through the openings and illuminates the alphanumeric characters. The touch sensor may have signal lines that are not visible through the openings. The signal lines may be transparent, may be covered by a diffuser, or may circumvent the openings so that they do not overlap.

  • Patent number: 7282181
    Abstract: A fluid collection and testing device includes a collection vial having a bottom and an open top along with an expresser sized for insertion into the vial open end. The expresser includes a ribbed base enabling fluid to pass therethrough and a support member holds the expresser within the collection vial with the ribbed base in a spaced apart relationship with the vial bottom. A fluid collector includes an absorbent member capturing a fluid and the absorbent member is sized for insertion into the expresser and is compressible against the ribbed base for releasing captured fluid through the ribbed base and into the vial bottom. A catch mechanism is provided for latching the fluid collector to the expresser after insertion into the expresser for enabling simultaneous removal of the expresser and the fluid collector from the collection vial.
