Filed:

Feb 17, 2012

Appl. No.:

13/399054

Inventors:

John F. Bulzacchelli - Yonkers NY, US
Steven M. Clements - Raleigh NC, US
Sergey V. Rylov - White Plains NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H03F 3/45

US Classification:

330261

Abstract:

Capacitive level-shifting circuits and methods are provided for adding DC offsets to the output of a current-integrating amplifier. For example, a current-integrating amplifier includes an input amplifier stage and an output offset circuit. The input amplifier stage includes an input node, a first output node, and a first switch connected between the first output node and a power supply node. The output offset circuit is connected to the first output node of the input amplifier stage and to a second output node of the current-integrating amplifier. The output offset circuit includes a first series capacitor coupled between the first output node of the input amplifier stage and the second output node of the current-integrating amplifier. The output offset circuit switchably connects a bias voltage to the second output node and charges the first series capacitor to add a DC offset to the second output node of the current-integrating amplifier.

Abstract:

A twist tie device for twisting together the ends of the tie ribbon and encircling an article which is positioned therein for tying is provided. The device includes a feed element for feeding the tie ribbon in the device to the article. An arm is provided for guilding the tie ribbon around the article. A twist head, connected to a rod, is provided for tightening the tie ribbon around the article. A gear assembly is provided for rotating and driving the twist head and for driving tie ribbon feed element. A cylinder with a rod plunger, forming an actuator, is coupled to the gear assembly. In response to a control signal, the actuator moves in a first direction between a start position, a first position and a second position. When the actuator moves from a start position to a first position, it makes contact with the arm so that the arm partially wraps the tie ribbon around the article. The actuator then moves to a second position and drives the gear assembly so that the twist head tightens the tie ribbon around the article.
