Door and Opener Repair:
garage door opener is a motorized device that opens and
closes garage doors. Most are controlled by switches on the
garage wall, as well as by remote controls carried in the
garage owner's cars
The electric opener
The electric overhead garage door opener was invented by C.G.
Johnson in 1926 in Hartford City, Indiana. Contrary to
popular belief, the electric opener does not provide the
actual lifting power to open and close a heavy garage door.
Instead, most of the actual lifting power comes from the
counterbalance springs that are under tension to lift the
garage door via steel counterbalance cables. The electric
opener only controls how far the door opens and closes, as
well as the force the garage door exerts. In most cases, the
garage door opener also acts as a lock.
The typical electric garage door opener consists of a power
unit that contains the electric motor. The power unit
attaches to a track. A trolley connected to an arm that
attaches to the top of the garage door slides back and forth
on the track, thus opening and closing the garage door. The
trolley is guided along the track by a chain, belt, or screw
that turns when the motor is operated. A quick-release
mechanism is attached to the trolley to allow the garage
door to be disconnected from the opener for manual operation
during a power failure or in case of emergency. Limit
switches on the power unit control the distance the garage
door opens and closes once the motor receives a signal from
the remote control or wall push button to operate the door.
The entire assembly hangs above the garage door. The power
unit hangs from the ceiling and is located towards the rear
of the garage. The end of the track on the opposite end of
the power unit attaches to a header bracket that is attached
to the header wall above the garage door. The power head is
usually supported by punched angle iron.
The first garage door opener remote controls were simple and
consisted of a simple transmitter (the remote) and receiver
which controlled the opener mechanism. The transmitter would
transmit on a designated frequency; the receiver would
listen for the radio signal, then open or close the garage,
depending on the door position. The basic concept of this
can be traced back to World War II. This type of system was
used to detonate remote bombs. While novel at the time, the
technology ran its course when garage door openers became
widely available and used. Then, not only did a person open
their garage door, they opened their neighbor’s garage
door as well. While the garage door remote is low in power
and in range, it was powerful enough to interfere with other
receivers in the area.
The second stage of the wireless garage door opener system
deals with the shared frequency problem. To rectify this,
systems required a garage door owner to preset a digital
code via dip switches on the receiver and transmitter. While
these switches provided garage door systems with 28 = 256
different codes they were not designed with high security in
mind; the main intent was to avoid interference with similar
The third stage of garage door opener market uses a
frequency spectrum range between 300-400 MHz and most of the
transmitter/receivers rely on hopping or rolling code
technology. This approach prevents perpetrators from
recording a code and replaying it to open a garage door.
Since the signal is supposed to be significantly different
from that of any other garage door remote control,
manufacturers claim it is impossible for someone other than
the owner of the remote to open the garage. When the
transmitter sends a code, it generates a new code using an
encoder. The receiver, after receiving a correct code, uses
the same encoder with the same original seed to generate a
new code that it will accept in the future. Because there is
a high probability that someone might accidentally push the
open button while not in range and desynchronize the code,
the receiver generates look-a-head codes ahead of time.
The fourth stage of garage door opener systems is similar to
third stage, but it is limited to the 315 MHz frequency. The
315 MHz frequency range avoids interference from the Land
Mobile Radio System (LMRS) used by the U.S. military.
Lavon is a city in Collin County, Texas, United States. The population was 387 at the 2000 census.
The community adopted the name Lavon in honor of Lavon Thompson, the son of E.C. Thompson, who operated the town's post office, established in 1888.
The flag stop, on what became the St. Louis Southwestern Railway of Texas in the early 1890's, served as a commercial center for farmers and increased the population of Lavon from an estimated twenty-five in the late 1880's to 300 by 1910.
In 1913 the Richard Royal chapter of the Daughters of the American Revolution marked the grave of John Abston, who was buried near Lavon. Abston fought in the battle of Kin's Mountain during the war, and later moved to Texas.
The population of Lavon Texas hovered near 200 through the 1930's and 1940's, and in 1940 five businesses served its residents. These population and business figures varied only slightly between 1940 and 1980, despite the construction of Lavon Lake in 1952-53, two miles west of town.
The lake did, however, bring boaters, fishermen, and picnickers to replace farmers as the most frequent visitors to the community. In 1980, the newly incorporated Lavon
TX had one business, serving 306 residents.
During the late 1990's and early 2000's, a number of smaller housing developments served to approximately double the population of Lavon, and brought the city's first new businesses in decades; an auto repair facility, a quick-stop grocery / gas station, a branch bank, barbecue restaurant, and others.
TODAY, Lavon Texas is on the verge of explosive growth, largely due to the introduction of the Grand Heritage housing development project, which will introduce an estimated 1900 new homes over the next seven years. By March of 2006, the first 300+ new homes will be a reality. New shopping centers have already arrived along Highway 78, with several more being planned.
