Abstract: The evolution in telecommunications whilst providing email, MMS, SMS, texting etc. still means that telephony is the only telecommunications format providing immediacy in respect of a recipient responding to a message from a sender. Within these other formats the recipient may view the message and elect when to respond thereby allowing them time to compose, consider, etc. rather than garnering their immediate reaction. Accordingly, it would be beneficial to add a level of immediacy to these other forms of telecommunications messaging.

Abstract: A linear compressor has a hollow piston with crown and sidewall. The piston reciprocates in a cylinder. A piston rod connects the piston to a spring. A connection between the piston rod and the piston transmits axial forces directly to the piston crown. The connection transmits lateral forces to the piston at an axial location away from the piston crown. The connection allows rotational flexibility between the piston and the piston rod transverse to and uniformly around the piston reciprocation axis. Other improvements in or relating to linear compressors are disclosed and claimed.

Abstract: A method for prevention of nozzle plate peel for inkjet printheads. The nozzle plate is bonded to the nozzle, with a layer of adhesive, and to a support, with a thicker layer of adhesive. This extra support prevents the peeling of the nozzle plate under the forces generated by, for example, a wiper blade passing over it. Spacers between the nozzle plate and support ensure the correct uniformity and constant thickness of the adhesive layer.
