摘要:
A hardware interface usable to communicate with electrically erasable read-only memory devices and, optionally, other external controls or devices, includes self-monitoring power supply circuitry, an EEPROM driver and noise and signal degradation prevention circuitry, and optional input/output circuitry which provides for programmatically cycling power to the memory device. The self-monitoring power supply circuitry is capable of determining whether a power supply has reached the hardware interface. The EEPROM driver and noise and signal degradation prevention circuitry reduces signal noise and/or signal degradation and driver circuitry for programming, monitoring, and downloading information to and from the EEPROM devices. The digital input/output circuitry is capable of controlling the power supply to the hardware interface, downloading or monitoring information to the hardware interface, or controlling/responding to external devices or controls.

A memory device authentication method that includes providing a memory device in a host device, and providing both an encryption algorithm, triggering the encryption algorithm during writing of data in the memory device, wherein the encryption algorithm allters the written data and generates a device altered data, then storing the written data in the memory device, running the encryption algorithm in the host device on the data written in the memory device and generating a host altered data, the verifying authenticity of the memory device by comparing the device altered data and the host alerted data. An authentication device and associated system that includes a host device that comprises a unit, a first encryption algorithm that is stored in the host device, and a second encryption algorithm, identical to the first encryption algorithm, that is permanently stored in a memory of the unit.

摘要:
An intelligent on-board monitoring system for replaceable module for a printing apparatus includes a memory element, an input for receiving information either from sensors on the replaceable module, or from the printing apparatus concerning printing operations performed, and a microprocessor connected to the memory for performing calculations upon data stored in the memory and upon the input information. The calculations produce results related to the performance of the replaceable module. These results can either be communicated to the printing apparatus, or used to control an adjustable operating parameter of the replaceable module itself, all without requiring computational resources of the printing apparatus itself.
摘要:
Systems and methods provide an acknowledgement protocol on completion of data transmission. A coupler board of a wireless identification system interfaces between a host processor of the wireless identification system and a replaceable unit monitor. The coupler board transmits data to the replaceable unit monitor. The replaceable unit monitor transmits an acknowledgement signal to the coupler board to indicate successful completion of the data transmission.

A product identification method and associated system may include providing an identification element that corresponds to a consumable product, the identification element at least one of being portable by a user and being readable by a scanner; and at least one of marking information related to the consumable product on the identification element and storing information related to the consumable product in the identification element. Also, a product identification device may include an identification element, and information related to consumable product which is at least one of marked on the identification element and stored in the identification element.
摘要:
An interface antenna is positioned between a tag antenna associated with a tag and a reader antenna associated with a reader. The interface antenna receives an electromagnetic carrier signal transmitted by the reader antenna and causes an increase in intensity of the electromagnetic carrier signal at the location of the tag antenna, thereby increasing the distance over which the tag can communicate with the reader. Where the tag is attached to a packaged object, the interface antenna may be included in the package to allow wireless data communication between the tag and a reader external to the package. For example, the interface antenna may be attached to a label on the package. At least a portion of the interface antenna may be formed from a conductive ink applied to the label and/or the container. The object may be a module, also known as a customer replaceable unit (CRU), and the tag may be configured as a customer replaceable unit monitor (CRUM).

A replaceable unit monitor reader system includes a host processor and a coupler board. The coupler board has a detection circuitry that provides an auto-detect, auto-initiate and/or auto-select ability. After receiving command from the host processor, the coupler board enables communication with a CRUM without requiring a further command from the host processor.

摘要:
Programming an electronic monitoring tag attached to a printing apparatus replaceable module includes electronically reading tag identification data from an electronic monitoring tag associated with the replaceable module, and electronically verifying that the tag identification data matches predetermined identification criteria. If the tag identification data matches the predetermined identification criteria, electronically programming the electronic monitoring tag with tag content.
