Patent GB-2186701-A (GB)
Title: Circuit testers
Inventor: OLIVER MARTIN JOHN
IPC: G06F11/22
Filed: 1986-02-14
Abstract: In circuit testers, notably automatic test equipment for the in circuit testing of digital devices, overheating damage can result if outputs are repeatedly 'back driven', that is whilst applying a test input to a first device, an output of a second connected device is forced into a state contrary to that it would normally adopt.The present invention provides a solution to the problem of damage by enforcing a cooling interval between backdriving test based upon a list of parameters representative of the backdriven device. In order to reduce the overall test time, a parameter is based on a measurement derived from a circuit of the type under test, and another on a subsequent backdriving test.A first test might result in device heating to a value 51 (Fig 5). A cooling interval τ<sub>coolp</sub> is enforced so that a subsequent test (resulting in heating to 54) may be made without exceeding device maximum allowable temperature T<sub>max</sub>.

IPC: B60B7/06
Filed: 1986-03-17
Abstract: An improved wheel trim retention system which may incorporate anti-theft features is disclosed herein which incorporate both an easily fabricated assembly for effectively preventing relative rotation between the wheel trim and associated vehicle wheel as well as providing an improved arrangement for aiding in centering and spacing of the outer periphery from the adjacent vehicle wheel structure so as to avoid annoying rattling noises emanating therefrom. The spacer centering members are particularly suited to accommodate situations wherein a single wheel trim is intended to be fitted to vehicle wheels fabricated from either aluminum or steel and incorporates a multi-position centering spacer member which is adapted to engage the adjacent annular flange portion of the vehicle wheel which may be positioned at different distances from the trim member. A retaining clip member is also provided which operates to retain the centering spacer member in assembled relationship with the wheel trim as well as to provide a biasing action to maintain it in a desired set position. In order to prevent relative rotation between the wheel trim and associated vehicle wheel, a plurality of spring fingers are provided on the trim member, selected ones of which are designed to engage recessed portions provided on the associated lock bracket so as to prevent the relative rotation therebetween. The number of spring fingers and recesses provided are coordinated in such a manner as to assure any desired number of spring fingers will be seated within the recesses simultaneously and yet also enable a relatively small degree of indexing in order to seat adjacent spring fingers.
