A security system that secures a building includes a weather detector for detecting weather conditions, such as thunder or high winds, which are likely to cause false alarms in sensors such as an acoustic glass break sensor, shock sensor and vibration sensor. The weather detector may include a sensing component that senses atmospheric conditions external to the building, such as temperature, pressure, wind speed and / or lightning. The weather detector may also include a component for receiving a data communication, such as from a radio, Internet, or telephone link, indicating that the weather condition is present in a vicinity of the building. The security system operates in a bad weather mode by requiring corroboration of intrusion detection signals from the sensors that can cause false alarms.

A point-to-point, wireless, millimeter wave communications link between two stations at least one of which is a mobile station. A millimeter wave transmitter system operating at frequencies higher than 57 GHz with a tracking antenna producing a beam having a half-power beam width of about 2 degrees or less and a millimeter wave receiver also with a tracking antenna having a half-power beam width of about 2 degrees or less. In preferred embodiments each mobile station has a global position system (GPS) and a radio transmitter and both tracking antennas are pointed utilizing GPS information from the mobile station or stations. The GPS information preferably is transmitted via a low frequency, low data rate radio. Each millimeter wave unit is capable of transmitting and / or receiving, through the atmosphere, digital information to / from the other station at rates in excess of 155 million bits per second during normal weather conditions. In preferred embodiments actually built and tested by Applicants digital information has been transmitted at rates of 1.25 gigabits per second. Preferred communication links described here are millimeter wave links operating at frequencies of 71-73 GHz and 74-76 GHz mounted on simple two-axis gimbals. Pointing information of the required accuracy is provided by GPS receivers and standard radio links which send the GPS calculated positions to the millimeter wave systems at the opposite end of the link. In these embodiments there is no need for any complicated closed loop pointing information derived from received signal intensity or phase. On moving platforms locally generated inertial attitude information is combined with the GPS positions to control pointing of the gimbaled transceivers.

A system and method for generating and delivering to users combined personalized traffic and weather report and alerts including forecast traffic and weather conditions. A user defines a travel route of interest and alert conditions. Based on current weather information, weather forecast information, current traffic information, and forecast traffic conditions a combined traffic and weather report for the user specified route is generated and delivered to the user via the internet and / or a wireless communications channel. The combined report may include a graphic display on a map background showing traffic conditions with a graphic representation of weather conditions overlaid thereon along with a tabular representation of traffic and weather conditions including forecast traffic and weather conditions for a plurality of future time periods. Alerts are generated and delivered when the traffic and weather alert conditions are satisfied.

Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy “ID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”. In conjunction with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.

A weather station (100) for indicating weather conditions, comprises a casing (110) having a screen (120) and an internal electronic operating circuit (90). The operating circuit (90) includes at least one sensor (70) for sensing an atmospheric parameter and a microprocessor (80) for ascertaining a weather condition based on the sensed atmospheric parameter and indicating the weather condition on the screen (120). The operating circuit (90) includes a memory (60) which stores several sets of images, each set representing a corresponding variation of the weather condition, for selection by the microprocessor (80) to indicate the weather condition in the variation as ascertained in an animated representation.

A lightweight insulated cover which may be easily installed and removed from an above ground spa has a top section and four side walls coupled to the top section. The top section and the four side walls comprised of an insulated layer, and a second layer coupled to a front and back surface of the insulated layer for protecting the insulated layer from moisture generated from the above ground spa and external weather conditions.
