A removable hard disk drive storage system includes a data storage cartridge having a write protect switch, and a reader configured to couple to and read data from the data storage cartridge. The reader includes a physical block that aligns with the write protect switch of the data storage cartridge. The physical block aligns with the write protect switch of the data storage cartridge to prevent the reader from coupling to the data storage cartridge when the write protect switch is in a write protect position.

A field configurable vehicle armoring system and associated method allow a user to retrofit and reconfigure a combination of armor components in response to a perceived threat change and using original equipment manufacture fasteners and holes. The system includes pillar armor attachable after an original equipment manufacture door and hinge are removed. Fasteners extend through the hinge of the armored door, the pillar armor and an original equipment manufacture pillar using holes other than the original equipment manufacture holes. Rocker panel and underbody armor is further provided, along with a ballistic resistant windscreen and rear wall armor. Where desired, system armor includes a composite plate comprising a strike face that is constructed from softer metallic material than an inner metallic sheet.

A tape reel assembly including a hub, opposing upper and lower flanges, a plurality of reel teeth, and three engagement features. The opposing upper and lower flanges extend in a radial fashion from opposing sides of the hub. The reel teeth extend axially outwardly relative to the hub. The three engagement features are equidistantly spaced within the reel teeth and are configured to provide a dominant mating surface relative to surfaces of the plurality of reel teeth. With this configuration, the three engagement features mate with teeth of the tape drive clutch, and prevent meshed engagement with the remaining reel teeth. Thus, the three engagement features dictate the plane of contact between the tape reel assembly and the drive clutch, with the reel teeth serving as general guide surfaces that facilitate this interaction. The engagement features can be pronounced drive teeth or reduced-sized valleys.

A flip-flop includes a data storage node for driving an inverter (62) and transfer gate (64) combination to transfer data stored on the data node (60) to a master storage node (66). A master cross-coupled latch (68) has two cross-coupled inverters (72) and (74) connected thereto such that the master storage node (66) is only connected to one side of the latch (68). The data node (66) directly drives a slave stage comprised of an inverter (76) and transfer gate (78) which in turn drives a slave storage node (80). The slave storage node (80) is connected to a slave cross-coupled latch (82) comprised of cross-coupled inverters (86) and (88). The slave storage node (80) comprises the Q-output of the inverter. The data is transferred to storage node (66) on the negative going edge of the clock signal and latched thereto on the positive going edge of the clock signal. ON the positive going edge of the clock signal, data is transferred from the storage node (66) to the slave storage node (80) and then latched in the latch (82) on the negative going edge of the clock signal. This results in a minimum number of inverters, thus decreasing the Clock-to-Q time.

The specification discloses an input transistor (14) which is variable between high and low impedance states in response to input voltage transitions at terminal 10. An output transistor (16) is coupled to the input transistor (14) and is responsive to an input transition at terminal 10 for changing impedance states. Circuitry including a speed up transistor (44) is coupled between the input transistor (14) and output transistor (16) for applying added current to the output transistor (16) to speed the change of impedance state. The circuitry applies added current to output transistor (16) until the output voltage at terminal (18) falls below twice the base-emitter voltage of the output transistor (16).

A high speed, noninverting circuit for providing an interface between transistor-transistor logic gates and Schottky transistor logic gates. In one embodiment the output of a TTL circuit is coupled through a Schottky diode to an emitter-follower whose input is Schottky clamped. The output of the emitter-follower is coupled to a constant current sink and to the cathode of a low barrier Schottky diode, the anode of which forms the STL-compatible output of the interface circuit. The present circuit thus performs a noninverting level translation with minimum propagation delay.

A storage device for storing photographic exposure information employs a closed-loop analog-to-digital (A-D) converter circuit includes a counter and a digital-to-analog (D-A) converter. The influence of erroneous signals which are created at the output of the D-A converter when the exposure information is stored in the counter is eliminated. The D-A converter circuit employs a ladder network of coarse accuracy. The stored exposure value, however, is highly accurate because of the closed-loop nature of the A-D converter circuit. Means responsive to the stored value for operating the exposure system of the camera are disclosed.
