Switch in high-power standby
dbSpectra has introduced the DBS-112AA antenna switch console, which operates from 30-960 MHz and controls a TX and an RX antenna switch.
The switch panel controls remotely located RF switches up to 200 feet from the panel.
These RF switches, which are included with the DBS-112AA, can be used to connect to standby antennas if the main antennas fail.
The DBS-112AA can be switched on site through a manual switch or it can be controlled remotely to switch in the secondary antennas. The switch panel will send a signal to the transmitter to disable and wait for verification before the TX switch is made.
Once the switch to the secondary TX antenna is complete, the DBS-112AA will notify the transmitter that it is safe to transmit.

Linear Technology rolls out converter
Linear Technology Corp. has introduced the LTC4410, a USB power manager IC in a ThinSOT package, which enables simultaneous battery charging and system operation of a Li-Ion powered USB peripheral from a USB host.
Compared to conventional methods, the LTC4410 powers the system load directly from USB’s 5V supply instead of the battery’s 3.6V terminal, allowing the battery to charge up to 39 percent faster. More charging current reduces the battery’s charging time and ensures a full charge while the peripheral is connected to the USB host device.
By managing the total current consumption, the IC permits a 1-cell Li-Ion battery powered USB peripheral to charge its battery and operate its system circuitry without exceeding a user set current limit.
Applications include USB certified Li-Ion powered devices such as portable printers, digital cameras, cell phones, and PDAs.
The LTC4410 ensures that a portable device is in compliance with USB overcurrent specifications by keeping the total current constant from the USB port.
This is accomplished by adjusting the charge current relative to the amount of current demanded by the system load. Immediately after the USB cable is detached from the peripheral device, the LTC4410 routes the system load to the battery for seamless and continuous operation of the end-device.
The LTC4410’s solution uses 15 fewer components than comparable solutions and fits into one fourth the board area.
The LTC4410 is offered in a six-lead ThinSOT package and is used with the LTC4053 Li-Ion battery charger for USB applications or LTC1733 for general purpose Li-Ion battery charging.
Pricing for the LTC4410 starts at $1.20 each in 1,000-piece quantities.
Fastpic software upgraded
The new access restriction feature of FastPicIC (Inventory Control) software from FastPic Systems allows companies to control access to specific trays, carriers and bins in automated storage and retrieval systems such as Vertical Lift Modules (VLMs), vertical and horizontal carousels.
The access restriction feature improves the security of automated storage and retrieval systems by locking out non-authorized personnel. It is particularly useful in applications where consumable and/or high-priced items such as electronic components and equipment, tools and supplies are stored.
The FastPic IC access restriction feature allows full customization of accessibility to storage and retrieval systems within two clicks. The system can be programmed to limit access by individual employee or department allowing operators to have access to only the items necessary to conduct their business.
The software can be re-programmed within the supervisory levels quickly and easily to meet changing employee and department security needs. Supervisory reports can also detail who had access to which inventory and when.
FastPic IC software is part of a suite of FastPic inventory management software products. FastPic IC is a basic inventory control and management software, providing operators of automated storage and retrieval systems the capability to simply enter a part number into the system and have the stored items automatically delivered to them. It is designed to be installed quickly and cost effectively using an installation wizard to create a basic parts inventory by stocking keeping unit (SKU) number and quantity.

Microwave Radio rolls tape
Microwave Radio Communications plans to highlight its Reporter radio at the National Association of Broadcaster’s Convention in April.
The Reporter is the latest advancement in MRC’s COFDM technology for portable and mobile microwave transmitter applications. It is a digital wireless camera-back radio that includes inboard MPEG II coding and COFDM modulation. It is lightweight (1.02 Kg) and consumes less than 18 watts of DC battery power.
The REPORTER can transmit up to 250 mW of output power at 2 GHz when operating in QPSK, 16 QAM or 64 QAM.
The radio supports up to 9 independent preset configurations — selected using a front-panel rotary dial switch and are loaded via a RS-232 port using Pro-Man software. The Pro-Man software allows the user to easily configure the radio for a specific application. The software is a common visual basic program that uses four separate headings for easy configuration support — RF channel frequency/mpeg video, mpeg audio, COFDM and service name/encryption requirements.
U.S. military trials had robots equipped with the Reporter radio transmitting live video from confined areas back to mobile and fixed command centers.
Broadcast trials have included a camera equipped with the REPORTER being carried through a network facility, floor-to-floor, room-to-room transmitting live video back to the studio.
The Reporter can be camera-mounted, mounted on a belt clip or a backpack. A small vehicle mount may be used for a motorcycle, bicycle, or other small vehicle.
Brackets to pole mount the transmitter are also available.
