Sensoray: Embeddable DVR with Incremental Encoder Interface
Tigard, OR — Sensoray has introduced its new Model 4012, a compact digital video recorder (DVR) designed for embedding in OEM systems. It records audio and video (A/V) to USB storage media in MP4 format and captures JPEG images on-the-fly without interrupting recording. Two incremental encoder interfaces allow
position information to be overlaid directly onto the video. The A/V outputs allow live video, record- ed A/V or JPEG snapshots to be displayed on an external monitor. Date and time are maintained by a real-time
clock with battery backup. To implement a com- plete embedded DVR, simply connect power, a cus- tom keypad and a USB storage device. The board encodes standard NTSC/PAL composite video using efficient H.264 compression. Audio from the onboard micro-
phone or stereo line-level inputs is digitized and compressed using AAC encoding. The compressed A/V streams are multiplexed and recorded as MP4 files, with file names auto- matically generated by the real-time clock. Bit rates can be tailored to match application requirements and storage capacity. Encoder counts are tracked by
the incremental encoder interfaces, and automatically scaled to user- configurable displacement units, such as meters or feet. The text overlay generator can
locate the current date, time and incremental encoder positions any- where in the video frame. The date, time and encoder position text is automatically updated every video frame.
KOA Speer Intros Molded Current Sense Resistor
Bradford, PA — KOA Speer Elec - tronics has added the SLW1, a 1.5W, 2512 size chip to its line of molded current sensing resistors. The SLW1 has resistance values
that range from 3 to 100 mW in sev- eral tolerances as low as 0.5 percent with a wide operating temperature range of –55 to +180°C (–67 to +356°F). The chip’s special electrode
shape absorbs thermal expansion and shrinkage stress easily. It is made with a flame-retardant, mold- ed construction, which provides high mechanical stability. The resistors are suitable for reflow, wave and iron soldering. The resistors are suitable for
the industrial, automotive, telecom- munication, and consumer electronic markets, in applications such as DC- DC conversion and AC adaptors, notebook PCs, battery packs, motor controls, automotive engineering and management systems, and low- impedance connections. In addition, the SLW1 molded current sense
resistor is AECQ200 qualified. Contact: KOA Speer

Model 4012 embeddable DVR.
An external USB storage device is required for DVR operation. If desired, a second USB stor-
age device may also be connected and the 4012 will simultaneously record to both devices. USB con- nectors are located on both sides of the board to facilitate connection to both removable and embed- ded storage devices. The DVR user interface consists of a user-sup-
plied keypad working in conjunction with the board’s onscreen menus. Each keypad connector pin can be routed to any keypad switch and configured to match the control scheme of the custom keypad. If preferred, a standard keyboard can be plugged
into any USB port and used to control the DVR. Contact: Sensoray, 7313 SW Tech Center
