King Design Industrial Co., Ltd.
This tester is designed to assess the damage made to product packaging and internal objects caused from transporting environment; to discover the packaging flaw and product’s early failure from a long-term cumulative vibration fatigue; avoid man-made transporting damage and improve product’s reliability and quality of delivered products. With the use of high-performance foot absorber, the resonance effect to floor caused by the bounce test may be waived; and can reduce the pile’s destruction to industrial plants. Two displays can make comparative display on both frequency and rpm at the same time; thus no need to switch in order to read these two values. The dual-control mode of time accumulator and counter can avoid human error resulting from the conversion. Easy to operate; no need for complicate training program.

Time-Resolved Electrochemical Quartz Crystal Microbalance
400C Series
-
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).

MEMS-Scanner Evaluation-Kit
-
The "QSDrive Scan Kit" evaluation kit enables small and medium-sized companies in particular to operate ResoLin components from the Fraunhofer IPMS in accordance with the specifications without the time-consuming in-house development of control electronics. The evaluation kit consists of a ResoLin component – a cardanic MEMS scanner with a linear axis and an optional, orthogonally oriented resonant axis – and control electronics that enable the components to be operated with an optimized trajectory supplied. The component is held by a scan head, which is also included in the scope of delivery and which, thanks to its special construction, can easily be integrated into common optical test setups. Depending on the design of the MEMS component, controlled operation of the component and synchronized operation of the resonant axis are also possible. The function is controlled by software that communicates with the electronics via USB.

Dielectric Resonator Oscillators
-
Dielectric resonator oscillators (DRO) are free running oscillators that utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals with excellent frequency stability. In addition, these oscillators are equipped with an internal voltage regulator that further improves the frequency stability by isolating the external bias pushing and modulation. In general, these oscillators are fixed. However, a small mechanical or electrical tuning range can be achieved by use of a self-locking screw or an integrated Varactor diode. The standard offering covers the frequency range of 2 to 40 GHz. While standard models are equipped with female SMA and K connectors at the RF port, other RF interface options are also available.

The design and modeling of microelectromechanical systems (MEMS) is a unique engineering discipline. At small length scales, the design of resonators, gyroscopes, accelerometers, and actuators must consider the effects of several physical phenomena in their operation. Consequently, COMSOL Multiphysics is ideally suited for MEMS applications.

Modern physics is the post-Newtonian conception of physics. It implies that classical descriptions of phenomena are lacking, and that an accurate, " Modern", description of nature requires theories to incorporate elements of quantum mechanics or relativity, or both. This section includes many of the most important experiments in physics, including e/m tubes, the Franck-Hertz experiment, and nuclear magnetic resonance (NMR)

SERS (Surface Enhanced Raman Scattering) Substrate & SERS Reader – Mini Chemistry Analytic Pack
-
The porous carbon SERS substrate provides not only high signal enhancement due to its strong broadband charge-transfer resonance for large chemical enhancement (as opposed to electromagnetic enhancement in traditional metal-based SERS substrates), but also extraordinarily high reproducibility or substrate-to-substrate, spot-to-spot, sample-to-sample, and time-to-time consistency in SERS spectrum (which is not possible with traditional metal-based SERS) due to the absence of "electromagnetic hot spots" by making the entire surface of the substrate "chemically hot", high durability due to no oxidization, and high compatibility to biomolecules due to its fluorescence quenching capability.
