Abstract: An articulated light shade including a stand having a first portion and a second portion, where the first portion is stiffer than the second portion, and the first portion defines a longitudinal axis. The second portion is flexible such that the second portion is movable relative to the first portion. A screen is coupled to the second portion of the stand, wherein the screen is rotatable about the longitudinal axis and tiltable relative to the longitudinal axis.

Abstract: A payment reader includes a tamper detection system having a first sensor element disposed on a circuit board of the tamper detection circuit; a second sensor element disposed within an interior surface of a housing of the tamper detection circuit; and a guard ring disposed on the circuit board of the tamper detection circuit configured to form an electrical connection with the first sensor element in response to injection of conductive fluid thereby indicating tampering with the tamper detection circuit, wherein the guard ring is configured to be on a plane different from the first sensor element to prevent unintentional activation of the tamper detection circuit.
