Definitions

• This invention relates to a badge and/or tag worn by a person or fixed to an asset which actively transmits signals for locating and tracking such person and/or asset within a facility. More particularly, the invention concerns a universal attachment member for an active personnel badge and a mounting arrangement for light sources in a tag attached to assets BACKGROUND OF THE INVENTION
• Badges and tags worn by persons or fixed to assets which actively transmit signals are well known.
• the signals transmitted by these badges and tags are detected by receivers positioned within a facility to locate and track such persons and assets Generally speaking, the badges and tags which transmit signals are called active badges and tags.
• the signals that are transmitted by these badges and tags are infrared signals.
• other types of signals, such as radio frequency or ultrasonic signals might be transmitted from such badges and tags.
• the active badge or tag that transmits an mfrared signal will include one or more light sources for the infrared signal, an integrated circuit board for the electronics, and a source of DC power such as one or more batte ⁇ es.
• the light sources, electronics and batte ⁇ es are usually housed within a housing having a front panel and a back panel.
• the back panel will include a device for attaching the badge or tag to a person or asset.
• the front panel of the housing will include one or more openings permitting the transmission of the infrared signals through the openings for detection by the receivers positioned within a facility.
• the attachment device permits only one method of attachment.
• the attachment device is an alligator clip mounted on one end of a plastic stnp which has its other end connected to the badge. The alligator clip is then clipped to the pocket or other surface on the person.
• tags that are attached to assets may be placed on the asset at any position except the bottom. This is generally true because the asset may have various shapes and sizes so that limited space is available for attaching the tag.
• the tag is attached to the asset in a particular position, the light being transmitted from the light source in the housing of the tag may not be directed toward a receiver in the facility. Thus, the receiver may not be capable of detecting the presence of the light source.
• the infrared signal is produced by a single light source having a limited beam width.
• the present invention is directed to a universal attachment member for use with a personnel badge that permits the badge to be attached to a surface of the person or the badge to be attached to a strap which hangs around the neck of the person.
• the person using the badge may elect to either attach the badge to a surface on the person or to have the badge hang around the neck of the person.
• the front panel of the badge through which the light is transmitted it is important that the front panel of the badge through which the light is transmitted, always faces outwardly from the person.
• the present invention also relates to the use of multiple light sources and a mounting arrangement for those light sources within the housing of an asset tag to insure that infrared light is transmitted 360° in a broad band so that the light can be detected by receivers in a facility regardless of where the tag is attached on the asset.
• a badge to be worn by a person in a locating and tracking system where the badge can be attached to a surface on the person or be attached to a strap which is worn around the neck of the person.
• an attachment member which includes a mounting plate mounted on a back panel of the badge, a pivoting plate having a portion for engaging the mounting plate, a pivot connector for pivotally connecting the pivoting plate to the mounting plate, and a biasing member for normally biasing the pivoting plate toward the mounting plate whereby the badge can be clipped to a surface on the person. It is a further object of the present invention to provide an attachment member which includes a channel for receiving a strap to be worn around the person's neck whereby the badge can be hung from the person's neck.
• the channel is formed by two openings in the pivoting plate which are positioned in spaced relation to the longitudinal axis of the badge and in the same vertical plane perpendicular to the longitudinal axis so that the strap passes through both openings in sufficient spaced relationship to make it difficult for the badge to twist on the strap and thus minimize the possibility that the light being transmitted from the badge will not be received by the receivers in the facility.
• the channel is formed by tabs extending downwardly from the upper portion of the pivoting plate and an intermediate portion of the pivoting plate, and the channel has openings at its ends which are spaced from the longitudinal axis of the badge to minimize the possibility that badge will become twisted.
• a first light source is mounted on the surface on the longitudinal axis of the tag and second and third light sources are mounted on the surface in spaced relationship to the longitudinal axis.
• the second and third light sources are mounted on the surface in a vertical plane transverse to the longitudinal, and the first light source is mounted on the surface in spaced relationship to such vertical plane.
