A linear actuator includes an actuator mechanism, a telescopic mechanism and a quick release mechanism. The system is responsive to selection of one or more objects by incorporating the object in a hypertext markup. The device further comprises biometric circuitry adapted to generate and store an initialized biometric template upon presentment of the person’s unique biometric parameter to the biometric interface unit. A transforming part transforms the low-band speech signal into a frequency range. In order to avoid potential hijacking attacks from entities other than the WCD, the home agent may, in conjunction with an authentication server, attempt to validate that that first NAI and second NAI are both associated with the WCD. Depending on one or more conditions, the first entity either uses the resource to render at least one ad or allows a second entity to use at least a portion of the resource to render content.
