A system and method of using a blower device to maintain an inflatable carnival attraction at a level of inflation safe for using the inflatable attraction, wherein the blower device operates on electrical energy received from an external source, monitoring the electrical energy, and triggering an alarm if the electrical energy is insufficient for the blower device to maintain the level of inflation safe for using the inflatable attraction, wherein the alarm is of sufficient loudness to be heard by personnel operating the attraction at a location distant from the blower device.

An inflatable structure includes a first inflatable section having an interior open to an airflow from a blower, and a second inflatable section attached to the first inflatable section and having an interior that is substantially closed from the airflow such that if the airflow is stopped the second inflatable section will not deflate as fast as the first inflatable section and will support the first inflatable section.

An inflatable includes an inflatable portion having an inlet couplable to a blower to blow air into an interior of the inflatable portion and an open weave section coupled to the inflatable portion and defining a wall or a window of the inflatable. An outer surface of the open weave section includes an image printed directly on the outer surface. In one option the image is a photo-quality digitally printed image having a resolution of at least 14 dpi.

A method and system for scrambling a plurality of input signals for secure transmission thereof, as well as various methods and systems for television transmission, are disclosed. The disclosed scrambling technique, in one form, includes modulating an in-phase component of at least one carrier signal in response to one and then another of a plurality of input signals in a sequence of time intervals such that parts but not all of the one and another of the input signals are carried by the in-phase component. A quadrature component of the at least one carrier signal is modulated in response to the one and another of the plurality of input signals in the sequence of time intervals such that parts but not all of the one and another of the input signals are carried by the quadrature component and such that the in-phase and quadrature components together carry the one and another of the input signals in their entireties. The modulated in-phase and quadrature components are combined for transmission. A decoder for unscrambling the plurality of signals is also disclosed.

Parts of a composite video signal, such as segments of each horizontal scan line, are stored in analog storage devices and retrieved therefrom in a cyclic manner to rearrange them and thereby encode the signal. The cyclic retrieval of the information from the storage devices is carried out on a selective basis in accordance with the binary state of a pseudo-random signal that is generated independently at each of the encoding and decoding stations. Synchronization of the two independently generated signals is provided by a control word and an initialization word that are transmitted with the encoded video signal, one of which is encrypted. Decryption of the word is carried out with a master key at each of the encoding and decoding stations.

An inflatable putting green apparatus includes a putting playfield that is selectively inflated or deflated. The putting playfield is inflated by forcing air into the putting playfield and deflated when the air is released from the putting playfield. The putting playfield includes an upper surface having a well positioned therein for receiving a golf ball. The putting playfield is flexible and is rolled up when the putting playfield is not inflated to allow for easy transportation thereof.
