Abstract: A single Airbed style earphone employing a standard three-conductor stereo headphone plug is adapted to enable the use of one earpiece to hear the combined left and right channels of stereo audio in a single ear. The single Airbed invention employs a three-conductor plug and is wired in such a way that it may be used equally well with both stereo and mono audio devices without the need for any kind of adapter, switch or sensing circuit. A pair of resistors matches the impedance load of a stereo headphone set.

Abstract: The prism glasses include movable prism lenses and, optionally. detachable temples. The movable lenses permit the user to alter the viewing angle from substantially 90 degrees downward to substantially 90 degrees upward. The glasses include a planar frame plate, a bridge, a forward outboard face and view ports therethrough. Two prisms, one for each view port, transmit the image. Prism frames have mounting elements for attachment and detachment to complementary mount elements on the frame. The mounts permit either rotation or removal and re-insertion on the frame. In a first mode of operation, the prism transmits a 90 degrees image. The prism mounts cooperate with the complementary frame mounts and the prism lenses can be (a) removed and re-positioned at a 180 degrees position or (b) moved 180 degrees from the downward 90 degree viewpoint to an upward 90 degree viewpoint to the second operational mode.

Abstract: The inventory tracking and purchasing method is deployed VOD interactive TV (STB-TV). Goods advertised with the shop on-demand (OD) process and the shop OD server, via the cable head end (HE) transmits an inventory sales indicator as metadata or configured VA to the STB-TV. The shop OD process displays the inventory scarcity indicia to the user. The shop OD server tracks goods available for sale based upon vendor supplied data or fictitious merchandising efforts. The sales indicator may be a time countdown to sell the goods. The time countdown is clock-based (STB) or metadata or VOD asset-based. Discount coupons may be sent as metadata or VA. The discount, time count and inventory scarcity indicator may be independent.

Abstract: The shop on-demand (OD) purchasing method includes an on-line shopping list compiled via a supplemental communications channel (cell phone, land line, Internet, etc.) or compiled via the shop OD VOD process. The list is displayed on the interactive TV (STB-enabled TV) via VOD menu or asset metadata or VOD-VA assets from the cable head end (HE) or shop OD client application operative at the cable HE. To motivate the user-buyer, complementary advertisements for related purchased-ordered goods are (a) compiled at the shop OD server and (b) displayed to the user via metadata or VOD-VA assets. External marketing incentives are sent via supplemental channels (discounts, time-limited offers, limited inventory offers and special sales). A transaction ID is sent to the cable HE with a promoted goods tag. At the shop OD server, a report for promoted goods is created for vendors.

Abstract: A multi-channel process enrolls user-viewers via VOD inputs and supplemental communications channels (cell phone, VoIP, land-line telephone, Internet or fax). Goods are advertised for the shop on-demand (OD) process via user's interactive TV (STB enabled TV set). A buy-now command is sent with the STB-ID code to the cable head end (HE) and shop OD client application operative thereat and to the shop OD computer server. If the set ID code matches the approved list at the HE, a purchase-confirmation is sent to the user via the STB-TV from the cable HE. One methodology sends a local confirm via metadata or specially configured VA asset. Supplemental communications channels handle supplemental confirms to the user. If not enrolled, supplemental communications network gathers user-viewer profile data. The profile lists user-selectable supple-comm message format (email, voice, text, fax). Non-enrollees may be given discounts to enroll. PINs are also used to control purchasing processes.

Abstract: The VOD purchasing method enables a user-viewer to purchase goods via a shop OD (on-demand) process on an interactive TV (STB enabled TV). The user selects shop OD goods and the STB-TV creates a transaction ID code with the STB-ID code or the cable head end (HE) or shop OD client application at the HE creates the trans-ID. The trans-ID is displayed on the user's TV. If created at the HE, the trans-ID is sent as metadata or configured VA to the STB-TV. Supplemental communications channels may deliver carry trans-ID to the user (cell phone, VoIP, land-line telephone, Internet or fax). User profile data is gathered via supple-comm channel lists purchasing limits (time, day, monetary, and PIN). The shop OD computer server limits purchases thereby. Financial fraud and abuse parameters are set at the OD server as are parental control parameters.
