An addressing device and method for addressing an addressed device configured to be removeably engaged with the addressing device. The addressing device includes a series of addressing device contacts that are individually and selectively configured to move from a first contact position to a second non-contact position via a respective switch. In the first contact position, an addressing device contact forms an electrical connection with a respective addressed device contact when the addressing device and the addressed device are in the engaged position. In the second non-contact position the addressing device contact does not form an electrical connection with a respective contact of the addressed device. The sequence of continuity provided to the addressed device by the selective contact or non-contact of the addressing device contacts is used to set an address of the addressed device.

Improvements are disclosed to lighting fixtures, support structures, interconnecting cabling, and other subjects. An improved method allows precise control of the beams of high power, long throw followspots by means of a steering mirror motorized in two axes. The beam is first directed upwards from the followspot by a first mirror to the steering mirror above. The range of elevations through which the beam can be steered is increased by displacing the steering mirror relative to the first mirror such that the portion of the beam between them is not vertical.

An electrical connector assembly includes a first electrical contact device and a second electrical contact device. The first electrical contact device includes a plurality of conductors. The second electrical contact device includes a first portion, a second portion movable in a rotational and translational manner relative to the first portion, and an actuator movable between a first position and a second position. The first portion includes first electrical contacts, and the second portion includes electrical sockets. Each socket receives an associated conductor and includes a second electrical contact aligned with an associated first electrical contact. The second portion is biased away from the first portion. When the actuator is in the first position, the actuator inhibits translational movement of the second portion toward the first portion. When the actuator is in the second position, the second portion is movable toward the first portion to permit the second electrical contacts to engage the first electrical contacts.

The invention teaches how to establish 1 to 1 connection between a first group of n electrical signals to a second group of n electrical signals. A first connector half with a first group of n1 contacts equally spaced around a circle and a second connector half with a second group n2 connectors, also equally spaced around a circle, with n11=n2n. The angular extent of the individual contacts from the first group is e1, and that from the second group is e2. The angular extent of the gap between individual contacts from the second group is g2. Following relationship must be satisfied: e1<g2 and e2>(360/n1e1).

A switch interconnect means for connecting arbitrarily selected n contacts out of a first group of n1 contacts where (n11) n to n signals from a first group of n signals. The minimum number of signals required for doing this is n+(n1n)*n. A single pole switch is connected from each of the n signals from the first group to each of the n arbitrarily selected contacts from the first group of n1 contacts. Each of the remaining n1n contacts from first group, is connected to one end of a group of n switches. The other end of each switch from this group of switches is connected to each of the n signals from second group.

A lever (24) mounted on a male housing (10) is formed with a connecting cam surface (29) capable of pressing a cam pin (41) of a female housing (40) while being kept out of contact with cam projections (23) in the process of rotating the lever (24) from an initial position to a connection position, and the lever (24) is formed with an escaping space (31). In the process of rotating the lever (24) from the initial position to the connection position in a state where the male housing (10) and the female housing (40) are separated and the moving plate (18) is at a protecting position, the cam projections (23) of the moving plate (18) are accommodated into the escaping space (31) while being kept out of contact with the connecting cam surface (29).
