A point of sale (POS) device includes an output device such as a speaker, a display screen, or a network interface. The POS device also includes a secure enclosure housing a secure processor and tamper detection circuitry for detecting attempts to tamper with the secure enclosure. Use of the output device is shared between the secure processor and a main processor via a switch that is controlled by the secure processor. The secure processor can switch control of the output device from the main processor to itself and can output an output dataset via the output device in a number of scenarios. These scenarios include the secure processor detecting an attempt to tamper with the secure enclosure, the secure processor recognizing that the main processor is behaving suspiciously, or the secure processor wanting to output sensitive information. The output dataset may include visual data, audio data, or network data.

Controlling processor's access to interface device

Wireless communication and proximity-based feedback technologies are disclosed. In some examples, a system identifies, based on analysis of signal(s) (e.g., conveying transaction object information) received by a reader interface from a transaction object in response to physical proximity between the transaction object and the reader interface, an indication of a movement of the transaction object relative to the reader interface. The system generates, based on the indication, feedback indicating a recommended change to the movement to improve an ability of the reader interface to read the transaction object. The system sends the feedback to an output device that to output the feedback to indicate the recommended change. The system reads the transaction object information from the transaction object using the reader interface in response to an improvement in the ability of the reader interface to read the transaction object and in response to the output of the feedback.

Movement feedback based on reader interface

Controlling access to output device between two processors

Wireless communication and proximity-based feedback technologies are disclosed. In some examples, a system identifies that a wireless communication interface has received wireless signal(s) for conveying information from a transaction object in response to proximity between the transaction object and the interface. The system identifies, based on relative signal strength of the signal(s) as received at each of a plurality of antennae of the interface, an indication of a relative position of the transaction object relative to the interface. The system generates, based on the indication of the relative position, feedback indicating a recommended movement of the transaction object relative to the interface to increase signal strength, and sends the feedback to an output device to output the feedback to indicate the recommended movement. The system reads the information from the transaction object using the interface in response to an increase in signal strength and to the outputting of the feedback.

Reader detection signal based proximity feedback

Sharing output device between unsecured processor and secured processor

A transaction object reader receives a signal from a user's transaction object when the user's transaction object is in proximity with the transaction object reader. This signal is conveyed from the transaction object reader to a secure processor that reads transaction information from the signal, generates a processed dataset by encrypting or otherwise processing the transaction information, and outputs the processed dataset to a main processor, which uses the processed dataset to conduct a transaction. The signal from the transaction object reader is also conveyed along a second path that bypasses the secure processor, instead going to a filter that filters the signal to attenuate the transaction information and then going to the main processor, which uses the filtered signal to provide feedback to the user identifying how close the transaction object is to the transaction object reader.

Reader detection signal bypassing secure processor

Erythropoietin analogs having at least one additional site for glycosylation, or a rearrangement of at least one site for glycosylation are disclosed. The invention also relates to DNA sequences encoding said erythropoietin analogs, and recombinant plasmids and host cells for analog expression.

Glycosylation analogs of erythropoietin

A meter run has a meter tube fitting of a configuration which includes an annular cavity. The cavity has confronting faces spaced from one another. An orifice plate holder is received in axially aligned relationship therebetween so that flow must occur through the central orifice formed in the orifice plate. A meter tube insert is positioned within the meter tube fitting and includes reduced diameter confronting annular flanges having faces spaced from one another substantially the same amount as the spacing of the confronting faces of the cavity. An adaptor assembly includes an outer annular gasket, an annular main support body, an inner annular gasket, and an orifice plate. The orifice plate is mounted within the inner annular gasket, the inner annular gasket is mounted within a passageway formed through the main support body, and the main support body is sealingly mounted within the outer annular gasket. The outer and inner gaskets, respectively, concurrently sealingly engage the confronting faces of the fixture and the insert, respectively.

A ball check valve assembly for assuring unidirectional flow through a meter run. The valve assembly includes a plate member adapted to be placed between the confronting flanges of a pipeline or meter run and positioned so that back flow cannot occur back through the meter run. A passageway formed through the plate member extends into an enclosure which has a valve seat formed on the top wall surface thereof through which unidirectional flow can occur. One wall surface of the enclosure extends up and then bends towards the plate member. The marginal free end of the bent part of the back plate member is apertured to admit the ball to be received therein, thereby capturing the ball between the seat and aperture in a manner that enables the ball always to gravitate back into sealed relationship respective to the seat, and yet the ball can be displaced sufficiently far enough from the seat to achieve relatively unobstructed flow.
