First, we discussed about Mouser Electronics' MEMS which enable medical innovation. MEMS sensors give consumers great time using its advanced features. MEMS, Micro ElectroMechanical Systems, are now on almost all electronic equipments, from consumer electronics, to home appliance, and now even reinventing and improving medical equipments.
Second, we had power electronic components for materials handling. Power electronics may be small but these components help drive heavy machinery. Variety of drives can be found in lift trucks, and other materials handling equipment. They supply the mechanical energy to move the motors for hydraulic pump and propulsion, even used as auxiliary actuators for steering.
Third, we had ultra-fast laser diode drivers. Technically, it is an ultra high-speed differential laser diode driver designed specifically to drive single junction laser diodes in a differential fashion. Theoretically, laser diode drivers work in two ways: 1) produce constant regulated voltage; 2) produce constant current drive though the laser diode load.
Fourth, we discussed about why datasheets for inductors do not indicated voltage rating. The voltage rating of an inductor is the maximum voltage that can be applied to the terminals without causing arcing or insulation breakdown. Voltage above the maximum rating may cause short circuits between turns, through the insulation, or from the windings to core or frame.
Now, we will discuss about the development platform with 2D multi-touch and 3D gestures. Microchip Technology's human interface input sensor, the 3DTouchPad. 3DTouchPad is Microchip's is a personal computer peripheral used to extend a 2D touch pad with 3D free space gestures. This component utilizes Microchip's projected capacitive (PCAP) sensor as well as Microchip's 3D gesture technology, GestIC®.
The 3DTouchPad offers all features expected from a touch pad (precision, multi-finger tracking, multi-finger surface gestures, such as swipes and scrolling) to which it adds 3D hand gestures. It enables a more efficient, more productive usage of the touch pad area. For example, the 3DTouchPad will allow the user to control the flow of pictures by a wave of the hand or to control the volume of the speakers with a casual rotation.
No driver installation is needed for the 3DTouchPad; it will simply work out-of-the-box.
The 3DTouchPad is designed to be a comprehensive development platform, offering a fully documented Software Development Kit (SDK) as well as an Application Programming Interface (API). The SDK contains reference code and enables the development of applications, drivers and games.
The 3DTouchPad consists of a single four-layer PCB enclosed by a plastic housing. The mini USB port provides connectivity to a USB port of a PC. Three LEDs indicate the operating modes: 2D, 3D and Debug mode.
Hardware Setup
The 3DTouchPad PCB contains the 2D touch pad surrounded by the electrodes for 3D gesture recognition. The assembly is placed on the bottom of the PCB. Figure 4 shows the assembly as well as the electrode structures.
3D gesture recognition is realized with Microchip’s single-chip gesture solution, MGC3130. The MGC3130 is a gesture recognition, motion tracking and approach detection controller based on Microchip’s patented GestIC technology. It enables user command input with natural hand movements while utilizing the principles of electrical near-field sensing.
MGC3130 is connected to four Rx frame electrodes (North, East, South and West) located at the top of the PCB and one transmit (Tx) electrode which covers a full middle layer of the PCB. The four Rx electrodes define the edges of the 3D sensing space (X and Y direction).
