HELIOT 300 series is a line of high-sensitivity portable helium leak detectors. The products offer a new vacuum design (select free flow test mode) which reportedly can detect leaks of all sizes. The units are also said to reduce test time and increase productivity when compared with traditional leak detection methods, and can be equipped with an optional dry backing pump to provide ultra-clean leak detection.
WaferAnalyzer 2.2 with camLine SPC is a software application designed to analyze production-related defect problems and monitor process variations through advanced trend identification. The product is said to provide rapid analysis of process defect issues as well as real-time process control. Applications include in-line process control and inspection tool control.
Metalarm Model HH-10 hand-held metal detectors from this company are designed to locate the exact position of small pieces of unwanted tramp material and then activate audio or visual alarms. The product can reportedly be used in any location where an in-line metal detector is installed, and can sense ferrous contamination as small as 1 mm, and slightly larger sizes for non-ferrous materials.
OJ family of sensors are said to offer high performance in a small package without the usual tradeoffs. The products feature automated setup/calibration and signal strength monitoring. Housings measure 24 × 45 × 11 mm. The products are available with either a laser or visible light source, have a reported 2,000 Hz switching speed, and have an IP68 rating for applications where moisture is present.
This company's 300 Series marker line now includes a portable and programmable model. The product is said to be capable of inscribing on almost any material, and can be configured as a stylus or a marker by changing the marking head. It is also said to produce very little noise, and can be hand held or suspended from a counterbalance.

Weld sensor
Weldthru sensors are designed to measure and control force and current to shorten cycle time and improve weld quality for safety critical or cosmetic welds. The product can be fitted with standard RWMA tapers or threads, and mounts directly in line with weld electrodes. Weld current and cooling water flow directly through the sensor while it measures force and current right at the welding point.
SI-702-B series electronic bi-axial tilt sensors are based upon force balance accelerometer technology to produce a high level, low impedance output proportional to the sine of the tilt angle. The product is also said to measure tilt along two perpendicular axes in strong vibration and shock environment through the use of electronic damping and desensitization circuitry.

Torque sensor
Non-contact wheel torque sensors from this company integrate digital FM telemetry and sensors into a single package which reportedly does not require an anti-rotation fixture. Features include non-contacting signal transmission, high-level analog signal throughput, RS-232 serial output, a battery-operated transmitter, and on-board shunt calibration and power switch.

Heated chucks
Thermofoil? heated chucks are designed to reduce weight and space while increasing temperature uniformity in semiconductor processing. Applications include lithography, CVD and PVD, dry etch, and stripping processes. Options include polyimide insulated heaters bonded to aluminum chucks, mica insulated heaters sealed into welded chucks, and mica insulated heaters clamped between silicone carbide plates.
This company's 1900 family of passive component testers has been approved for a CE mark. The line consists of the 1910 inductance analyzer and the 1920 precision LCR meter, with more models planned. Both products are designed for fast throughput in automated production testing of resistive, capacitive, and inductive components and materials.

Light Matters: Systems Level Approach to HBLED illumination applications
Its good practice to apply a systems-level approach to high-brightness LED (HBLED) illumination applications. Minimally, the system includes the optical, thermal and electrical characteristics of the of the HBLED, the lens (if any) which is built-in to its package, secondary optics such as external plastic lenses/reflectors to direct the light as your application requires and power driver electronics.
