Abstract

A Pluggable small form-factor UHF Radio Frequency ID reader having in an enclosure: a host CPU; volatile memory; non-volatile memory; power inputs; digital circuitry comprising the CPU and supporting components; analog circuitry comprising power and Radio Frequency components; one or more antennas; networking components; user interface components; debug and test components; WiFi subsystem; Radio Frequency ID subsystem; wherein said enclosure comprises thermal dissipation capacity, radio frequency transparency with WiFi and Radio Frequency ID antennas, provides protection from physical and radiofrequency forces, is mountable to an AC outlet and can also be mounted flush to a solid wall or surface or at an angle to a solid wall or surface, connectable to PoE or DC inputs, having a capacity to convert AC/DC current; Radio Frequency ID setting configurable, employs intelligent filtering and smoothing algorithms and transmits only relevant summarized information back over a network, and permits firmware management and real-time monitoring.

Claims

1. A Pluggable small form-factor UHF Radio Frequency ID reader comprising:

a mounting bracket; and

an enclosure comprising a host CPU, volatile memory, non-volatile memory, power inputs, digital circuitry comprising the CPU and supporting components, analog circuitry comprising power and Radio Frequency components, one or more antennas, networking components, user interface components, debug and test components, a WiFi subsystem, and a Radio Frequency ID subsystem;

wherein said enclosure comprises thermal dissipation capacity, radio frequency transparency with WiFi and Radio Frequency ID antennas, provides protection from physical and radiofrequency forces, is mountable to an AC outlet and can also be mounted flush to a solid wall or surface or at an angle to a solid wall or surface, connectable to PoE or DC inputs, having a capacity to convert AC/DC current;

Radio Frequency ID setting configurable, employs intelligent filtering and smoothing algorithms and transmits only relevant summarized information back over a network, and permits firmware management and real-time monitoring,

wherein said enclosure has a dome-shaped upper surface and a substantially flat back surface,

wherein said back surface of said enclosure comprises a mounting plate that is complementary to said mounting bracket for attachment to said mounting bracket, and

wherein said mounting bracket permits orienting of said mounting bracket in multiple angles to a mounting surface.

2. The reader of claim 1, wherein said reader communicates via 802.11 WiFi or Ethernet.

3. The reader of claim 1, wherein said reader has a removable plug.

4. The reader of claim 1, further comprising one or more of a reset button, LED, LCD displays, and sound output means.

5. The reader of claim 1, wherein said back surface has a recessed portion for receiving a removable plug.

6. The reader of claim 1, wherein said reader can read passive tags, battery assisted passive tags and battery powered tags.

7. The reader of claim 3, wherein said plug comprises one or more removable pins.
