Abstract: A band includes a latch body that is movable by pulling a tab. The latch body extends through an opening of the band and secures with a pin located on a head-mountable device. The band can detach from the head-mountable device by pulling the tab, which actuates the latch body and removes the latch body from the pin. A spring (or springs) can bias the latch body toward the opening, causing the latch body to enter the pin. An applied force to the tab can overcome the biasing force provided by the spring(s), and move the latch body away from, and out of, the pin.

Abstract: A system for controlling access to devices using direct connect protocols includes a network of computers, printers, personal digital assistants and servers. Client devices are programmed to embed one or more access codes in job streams (e.g., a word-processing file to be printed) when requesting services from other devices. A method includes a device (e.g., network printer) parsing a job stream received from a client device (e.g., computer) to find one or more embedded access codes, identifying each embedded access code that matches a stored access code, and authorizing one or more device features associated with each identified matching access code.
