Abstract: Multiple hardware and software external signaling safeguards are employed by an infusion pump to ensure proper operation and to prevent the possibility of overinfusion or underinfusion due to unauthorized signals. All communications with the infusion pump pass through a communications module, and a collection of interconnected controller cores process communications within the infusion pump. The communication module provides wireless and wired communication and manages all communications with the controller cores. Communication through the wired communication interface is only permitted when the infusion pump is not actively infusing. When the infusion pump is actively infusing, no communication via the wired communication interface is permitted. The validity of certificates from external wired and wireless signal sources are checked to ensure the source is authorized to communicate with the infusion pump. In addition, all communications are expected to utilize proprietary messaging protocols.

Abstract: A high frequency data network access system leverages commodity WiFi chipsets and specifically multi spatial stream (e.g., 802.11 ac) chipsets in combination with electrically steered patch array antenna systems at the subscriber nodes. In addition, for thermal control, the high frequency components are mounted to a main body that includes a heat sink and a chimney. These components are also separated from components operating at baseband to avoid interference.

Abstract: A machine and method of reducing duplicate transmission data employs one more more digests to track field/value pairs that have previously been distributed. Each digest contains a record table and a segment table. The record table includes anonymous identifier records, each of which contain an anonymous identifier and one or more indexes into the segment table. The segment table comprises an array of every existing data field/value pair. Before distribution of update data, each record is matched to an anonymous identifier record in the record table. The segment values in the prospective distribution record are compared to the digest's anonymous identifier record, used to determine which data has already been distributed, and thus will be suppressed in the distribution.

Abstract: A system and method for protecting biological or other material from contamination through the steps of filling, freeze-drying, packaging, storing and use are disclosed. A system can include a flexible container, a membrane configured to transmit air or solvent vapor out of the flexible container, and a membrane frame supporting the membrane and engaged with at least one column member. The at least one column member can be configured to maintain the membrane and the membrane frame a spaced distance from one or more contents received within the flexible container. Upon application of a downward force, the at least one column member can assume a collapsed configuration. A method can include inserting a biological material, for example, into a flexible container, freeze-drying the biological material, moving the freeze-dried biological material to a portion of the flexible container that includes at least one port, and sealing the biological material within the portion.

Abstract: A railroad switching apparatus utilizing a tie which is positioned under rails and points used in switching railroad cars. A support is interposed the tie and the rails and points and includes a passageway to guide the first and second indicator bars which are attached to the points. A slider is also employed at the attachment point of the indicator bars to the points to accommodate the thermal expansion and contraction of the rails and points. The indicator bars are formed into a coaxial unit in order to allow simple observation of the relative movement between the first and second indicator bars to determine proper movement of the points relative to the rails.
