Claw

A claw is a curved, pointed appendage, found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). However, the word "claw" is also often used in reference to an invertebrate. Somewhat similar fine hooked structures are found in arthropods such as beetles and spiders, at the end of the leg or tarsus for gripping a surface as the creature walks. Crabs', lobsters' and scorpions' pincers, or more formally, their "chelae", are sometimes called claws.

A true claw, (as opposed to a chela) is made of hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense, and grooming, in those and other species.

Similar appendages that are flat and do not come to a sharp point are called nails instead. Claw-like projections that do not form at the end of digits, but spring from other parts of the foot are properly named spurs.

Claws of animals like tigers, lions, and bears were used in making items such as ornaments, pendants, and brooches.

Sophie Treadwell

Sophie Treadwell (October 3, 1885 – February 20, 1970), was a noteworthy American playwright and journalist of the first half of the 20th century. She is best known for her play Machinal which is often included in drama anthologies as an example of a expressionist or modernist play. Treadwell wrote dozens of plays, several novels, as well as serial stories and countless articles that appeared in newspapers. In addition to writing plays for the theatre, Treadwell also produced, directed, and acted in some of her productions. The styles and subjects of Treadwell's writings are vast, but many present women's issues of her time, subjects of current media coverage, or aspects of Sophie's Mexican heritage.

Heritage and childhood

Sophie Anita Treadwell was born in 1885 in Stockton, California. Between 1890 and 1891, Sophie's father, Alfred Treadwell, deserted her and her mother and moved to San Francisco. Although Sophie originally excelled at school, after her father left she struggled, which others have attributed to the frequency with which she and her mother relocated. While Sophie primarily lived with her mother, occasionally Sophie would spend summers in San Francisco with her father. During these visits, Sophie was first exposed to theatre; she witnessed famous actresses Helena Modjeska and Sarah Bernhardt in The Merchant of Venice and Phèdre, respectively. In 1902, Sophie and her mother, Nettie Fairchild Treadwell moved to San Francisco.

USB

USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. It is currently developed by the USB Implementers Forum.

USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.

Overview

In general, there are three basic kinds or sizes related to the USB connectors and types of established connection: the older "standard" size, in its USB 1.1, 2.0, and 3.0 variants (for example, on USB flash drives), the "mini" size (primarily for the B connector end, such as on many cameras), and the "micro" size, in its USB 1.1, 2.0, and 3.0 variants (for example, on most modern mobile phones).

USB 3.0

USB 3.0 (renamed to USB 3.1 Gen 1 in 2015) is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer mode SuperSpeed (SS) that can transfer data at up to 5 Gbit/s (625 MB/s), which is about ten times faster than the USB 2.0 standard. USB 3.0 connectors are usually distinguished from their USB 2.0 counterparts by blue color-coding of the receptacles and plugs, and the initials SS.

A successor standard, USB 3.1 (renamed to USB 3.1 Gen 2 in 2015), was released in July 2013 with the new transfer mode SuperSpeed+ that can transfer data at up to 10 Gbit/s (1.25 GB/s, twice the rate of USB 3.0), bringing its theoretical maximum speed on par with the first version of the Thunderbolt interface.

Overview

The USB 3.0 specification is similar to USB 2.0 but with many improvements and an alternative implementation. Earlier USB concepts like endpoints and four transfer types (bulk, control, isochronous and interrupt) are preserved but the protocol and electrical interface are different. The specification defines a physically separate channel to carry USB 3.0 traffic. The changes in this specification make improvements in the following areas:

USB-6008

The National Instruments USB-6008 is a low-cost, multifunction data acquisition device (DAQ). It has 8 analog inputs, 2 analog outputs, and 12 digital input/outputs. The digital channels are divided into two ports. When one or more channels on each port is set to either input or output, the port is locked into that particular mode.

The USB-6008 uses the NI-DAQmx driver software and is compatible with LabVIEW, Measurement Studio for Visual Studio, .NET, LabWindows/CVI, and MATLAB (version R2006a and newer).
