De-bouncing is any kind of hardware device or software that ensures
that only a single signal will be acted upon for a single opening or
closing of a contact. When you press a key on your computer keyboard,
you expect a single contact to be recorded by your computer. In fact,
however, there is an initial contact, a slight bounce or lightening up of
the contact, then another contact as the bounce ends, yet another
bounce back, and so forth. A similar effect takes place when a switch
made using a metal contact is opened. The usual solution is a de-
bouncing device or software that ensures that only one digital signal
can be registered within the space of a given time (usually milliseconds)
A hydrocarbon (Alkane) flammable colorless liquid with ten carbon
atoms.
A logarithmic measure of the ratio of two signal levels. A practical unit
of gain.
A numbering system based on 10.
A value assigned or an action taken automatically unless another is
specified.
An incremental value in the temperature scale, i.e., there are 100
degrees between the ice point and the boiling point of water in the
Celsius scale and 180°F between the same two points in the
Fahrenheit scale.
Point at which gas leaves a transporter's system completing a sale or
transportation service transaction between the pipeline company and a
sale or transportation service customer.
That 24-hour period specified by a supplier-user contract for purposes
of determining the purchaser's daily quantity of gas used (e.g., 8 AM to
8 AM, etc.). This term is primarily used in pipeline-distribution company
agreements. It is similar to, and usually coincides with, the distribution
company "Contract Day".
The rate of flow of gas required by a consumer or a group of
consumers, often an average over a specified short time interval (cf/hr
or Mcf/hr). Demand is the cause; load is the effect.
