PostgreSQL as a Schemaless Database - The Build

PostgreSQL as a Schemaless Database. Christophe Pettus PostgreSQL Experts, Inc. OSCON 2013 Welcome! • I’m Christophe. • PostgreSQL person since 1997. • Consultant with PostgreSQL Experts, Inc. • cpettus@pgexperts.com • thebuild.com • @xof on Twitter. What’s on the menu? • What is a schemaless database? • How can you use PostgreSQL to store schemaless data? • How does do the various schemaless options perform? A note on NoSQL. • Worst. Term. Ever. • It’s true that all modern schemaless databases do not use SQL, but… • Neither did Postgres before it became PostgreSQL. (Remember QUEL?) • The defining characteristic is the lack of a fixed schema. Schematic. • A schema is a fixed (although mutable over time) definition of the data. • Database to schema (unfortunate term) to table to field/column/attribute. • Individual fields can be optional (NULL). • Adding new columns requires a schema change.

Installation Schematic - Hilborn Fuel Injection

INSTRUCTIONS: NOZZLES SET-UP RECOMMENDATION 1. The main line from the pump to the metering valve connects to the fitting at the top of the metering valve. 2. The Secondary By-Pass Valve connects to the brass fitting opposite the throttle arm on the side of the metering valve. There are no jets to change in this valve. 3. The Hi Speed By-Pass (Cut Off) Valve (not on all units) connects to a pump outlet and returns the fuel to the tank. Each change in the main jet size should be accompanied by a change in the spacers as follows: • For every .005 richer on the main by pass jet, add a 1/32" spacer. • For every .005 leaner on the main by pass jet, remove a 1/32" spacer.

AN264: USB FM Radio - Silicon Labs
by dietdude 0 Comments favorite 3 Viewed Download 0 Times

This USB FM Radio design is intended as a reference for incorporating FM radio functionality into a USB product. The design consists of two major components, the Si4701 FM radio receiver and the C8051F321 microcontroller with a built-in universal serial bus (USB) peripheral. Due to the high level of system integration of both of these components, the total design is very small with fewer external components than many other solutions. The software, firmware, schematic, and layout source for this design are located in AN264SW.zip. The latest version of these files as well as this document itself can be found at the following URL: http://www.silabs.com/usbradio The system consists of a Windows® application that communicates with the C8051F321 using the USB connection. The C8051F321 microcontroller controls the Si4701 using the serial peripheral interface (SPI). The Si4701 audio outputs are sampled using the C8051F321’s analog-to-digital converter (ADC) and sent to the host across the USB interface. The Windows application plays the audio using the PC speakers or headphones.

SolidWorks® Electrical simplifies electrical schematic creation with an intuitive interface for faster design of embedded electrical systems. Bidirectional integration in real time with SolidWorks 3D CAD provides better collaboration and productivity, resulting in fewer product delays, more consistent and standardized designs, lower costs, and faster time-to-market. Create schematic-driven harness designs with powerful routing, flattening, and automated documentation. SolidWorks Electrical schematics integrate with SolidWorks 3D models to enable true concurrent electromechanical design. Modernize your electrical system design In the complex world of electromechanical design, creating an electrical system using 3D CAD can be a demanding and daunting task. Developing design elements and defining the electrical interconnect of wires, cables, and harnesses is often laborious and error-prone. 3D CAD electrical development has typically been done with the interchange of design data via external files and manual design. Using external files can cause electrical and mechanical designs to become unsynchronized, resulting in design, manufacturing, and supply chain discontinuities. Current practices also do not provide easy collaboration between design disciplines. SolidWorks Electrical 3D™ technology enables faster development of schematically defined electrical systems that can be readily implemented in the 3D CAD model in a 3DEXPERIENCE environment synchronized between the electrical and mechanical design teams. Real-time synchronization of the electrical schematic and 3D CAD model enables unification of the bill of materials (BOM) between the electrical system and the mechanical design, eliminating errors from design changes.

Implementing An Ultralow-Power Keypad ... - Texas Instruments

Keypad Schematic Diagram. When a key is pressed, the column associated with that key gets a rising edge, waking the. MSP430. At that point, Timer_A is ... Often in applications with keypads, the condition can occur where a key can be held or stuck down, causing excess current consumption and reducing the battery life of a battery-operated product. This application report shows a solution. The keypad interface in this report, based on the MSP430, draws 0.1 µA while waiting for a key press, is completely interrupt driven, requiring no polling, and consumes a maximum of only 2 µA at 3 V if all keys are pressed and held simultaneously. The rows of the keypad are connected to port pins P3.0 – P3.3. The columns are connected to pins P1.0 – P1.2. Connecting the rows to port 3 pins, instead of port 1 pins, leaves the other port 1 pins for other interrupt sources, because the P1 pins have interrupt capability, but the P3 pins do not. In normal mode, while the circuit is awaiting a key press (wait-for-press mode), the rows are driven high, and the P1.x column pins are configured as inputs, with interrupts enabled and set to interrupt on a rising edge. The 4.7 MΩ pulldown resistors hold the inputs low in this state. The MSP430 is then put into low-power mode 4, where the MSP430 current consumption is about 100 nA. This state is maintained indefinitely until a key is pressed. The circuit is completely interrupt-driven with no need for polling.
