    •  DETAILED DESCRIPTION
  • FIG. 1 depicts a universal remote control device 10 and a charging base 12 for use with the universal remote control device 10. The universal remote control device 10 is configured to be operated by a user to remotely control a machine, such as a television as well as other electronic appliances, by sending wireless signals from the universal remote control device 10 to the machine.
  • The universal remote control device 10 includes a housing 14, which in the illustrated embodiment is hollow and generally box shaped. When in use, the universal remote control device 10 is often oriented as shown in FIG. 2. The housing 14 is dimensioned so as to be easily held with a single hand of a person similar to handheld devices such as mobile phones. The universal remote control device 10 will be described with reference to the orientation shown in FIG. 2 for ease of understanding how to make and use the universal remote control device. Directional terms will be used with reference to the orientation shown in FIG. 2; however, these directional terms are used for ease of understanding only and should not be used to limit the universal remote control device to any particular orientation unless specifically mentioned. The housing 14 includes an upper wall 16, a left (first) side wall 18, and a lower wall 20. The upper wall 16, the left side wall 18, and the lower wall 20 are integrally formed from a single piece of IR transmissive plastic in the illustrated embodiment. With reference back to FIG. 1, the upper wall 16 includes a plurality of speaker holes 24. The left side wall 18 is oriented perpendicular to the upper wall 16. The lower wall 20 is oriented parallel with the upper wall 16 and perpendicular to the left side wall 18. With reference to FIG. 3, the lower wall 20 includes first and second power contact openings 26, 28, respectively, and first and second data contact openings 32, 34, respectively. The lower wall 20 also includes a microphone hole 36. The plurality of speaker holes 24 in the upper wall 16 extend through the upper wall into the hollow interior of the housing 14. The power contact openings 26, 28, the data contact openings 32, 34 and the microphone hole 36 extend through the lower wall 20 into the hollow interior of the housing 14.
  • With reference back to FIG. 2, the housing 14 includes a right (second) side wall 40 opposite the left side wall 18 and interconnecting the upper wall 16 with the lower wall 20. The housing 14 further includes a front wall 42 and a rear wall 44. As more clearly seen in FIGS. 1 and 3, the right side wall 40 is beveled with respect to both the front wall 42 and the rear wall 44. The right side wall 40 includes a power button opening 46, a mute button opening 48, and a volume button opening 50. Each of these button openings 46, 48 and 50 extends through the right side wall 40 into the hollow interior of the housing 14. In the illustrated embodiment, the right side wall 40 is made from an extruded aluminum.
  • The front wall 42 connects together the upper wall 16, the left side wall 18, the lower wall 20, and the right side wall 40. In the illustrated embodiment, the front wall 42 is made from glass. The front wall 42 includes an indicator light opening 52. The rear wall 44 connects the upper wall 16, the left side wall 18, the lower wall 20, and the right side wall 40 together. The rear wall 44 is also made from glass in the illustrated embodiment, which is IR transmissive.
  • With reference to FIG. 4, the universal remote control device 10 also includes an infrared (IR) signal generator 60 (depicted schematically), which can be positioned in or on the housing 14. A plurality of IR signal generators are provided in the housing 14 of the universal remote control device 10 described herein and will be described in further detail below. If desired, however, only one IR signal generator 60 is necessary. The universal remote control device 10 also includes a user interface, which in the illustrated embodiment includes a graphical user interface (GUI) 62 positioned in or on the housing 14. The universal remote control device 10 further includes a control unit 64 positioned in the housing 14 and connected with the IR signal generator 60 and the user interface 62. The universal remote control device 10 also includes a battery 66, which in the illustrated embodiment is a rechargeable battery, positioned in the housing 14 and connected with the control unit 64. First and second power contacts 68, 70, respectively, are each connected with the rechargeable battery 66. Each of the first and second power contacts 68, 70 includes an external contact surface 74, 76 (FIG. 3), respectively, that is parallel, at least flush with, or outwardly offset from an unrecessed flat external surface 78 of the housing 14. In the illustrated embodiment, each external contact surface 74, 76 is outwardly offset from (although slightly) and parallel with the unrecessed flat external surface 78, which in the illustrated embodiment is located on the lower wall 20 of the housing 14. The location of the first and second power contacts 68, 70 could be changed such that the external contact surfaces 74, 76 extend from an unrecessed flat external surface located on another wall of the housing 14, for example on the rear wall 44 or elsewhere. The unrecessed flat external surface 78 on the housing 14 is devoid of concavity adjacent the external contact surfaces 74, 76 of the power contacts 68, 70. This facilitates alignment of the universal remote control device 10 on the charging base 12.
  • The control unit 64 can include a processor and other control circuitry and is powered by the rechargeable battery 66. The control unit 64 is electrically connected with a power switch 100 that can be operated by a power button 102 (FIG. 3) extending through the power button opening 46 in the right side wall 40. Pressing the power button 102 operates the power switch 100 and the control unit 64 can operate the IR signal generator 60 so that a power (ON/OFF) signal can be sent to a machine (or multiple machines) controlled by the universal remote control device 10. The control unit 64 is also electrically connected with a mute switch 104, which can be operated by a mute button 106 (FIG. 3) extending through the mute button opening 48. Pressing of the mute button 106 by an operator results in the control unit 64 controlling the IR signal generator 60 to generate a mute command signal to at least one of the machines operated by the universal remote control device 10. The control unit 64 is also electrically connected with volume switches 108 which can be operated by a volume button 110 extending through the volume button opening 50 in the right side wall 40. Operation of the volume switches 108 can result in the control unit 64 commanding the IR signal generator 60 to generate an IR command signal to change the volume on the machine operated by the universal remote control device 10. The control unit 64 can also be electrically connected with a microphone 114, which can be positioned near the microphone hole 36. The control unit 64 can also be electrically connected with a speaker 116, which can be located near the plurality of speaker holes 24. The control unit 64 can also be electrically connected with or associated with a memory 118, which can be RAM or ROM. The control unit 64 can also be electrically connected with a display 130 and a touch panel 132 associated with the display. The control unit 64 can also be electrically connected with an accelerometer 134. The accelerometer 134 is provided to detect when the universal remote control device 10 is picked up from a support surface so that the universal remote control device 10 can move from a sleep state to an ON state and display graphical images on the display 130. The universal remote control device 10 further includes first and second data contacts 138, 140, respectively, that are each connected with the control unit 64. Each of the first and second data contacts 138, 140 includes an outer contact surface 144, 146, respectively, that is parallel, at least flush with, or outwardly offset from the unrecessed flat external surface 78 of the housing 14. In the illustrated embodiment, the outer contact surfaces 144, 146 for each of the first and second data contacts 138, 140, respectively, are parallel with the external contact surfaces 74, 76 of the first and second power contacts 68, 70, respectively. The control unit 64 is also electrically connected with indicator lights 160, which can be LEDs positioned adjacent to the indicator light opening 52 in the front wall 42 of the housing 14. The universal remote control device 10 is also configured for wireless connectivity via IR, Wi-Fi, Bluetooth, ZigBee and Z-Wave. The control unit 64 is appropriately programmed and appropriate conventional antennas/receivers (not shown) are provided in the universal remote control device 10 for the aforementioned wireless connectivity.
  • As indicated above, the IR signal generator 60 can include a plurality of IR signal generators such as an upper IR signal generator 170 (shown in phantom in FIG. 1) and a rear IR signal generator 172 (shown in phantom in FIG. 5). The upper IR signal generator 170 is positioned in the housing 14 and configured to generate an IR signal through the upper wall 16 of the housing 14. The rear IR signal generator 172 is positioned in the housing 14 and configured to generate an IR signal through the rear wall 44 of the housing. As mentioned above, the universal remote control device 10 is configured to be a hand held device. As such when an operator handles the universal remote control device 10, her hand should not cover either the upper IR signal generator 170 or the rear IR signal generator 172. The user interface 62 for the universal remote control device 10 includes the GUI presented on the display 130 and associated with the touch panel 132. With respect to the front wall 42 of the housing 14, the display 130 is larger than typical displays on common electronic handheld devices. In the illustrated embodiment, the display 130 has an aspect ratio of 21:9. The GUI is controlled by the control unit 64 and all buttons 180 on the GUI for providing user input are positioned below the rear IR signal generator 172 toward the lower wall 20 of the housing 14. In the illustrated embodiment, the rear IR signal generator 172 is positioned between an upper edge 182 of the display 130 and the upper wall 16 of the housing 14 (compare FIG. 2 to FIG. 5). As such, the likelihood of an operator inadvertently covering the rear IR signal generator 172 is mitigated when the operator is holding the remote upright as shown in FIG. 2 because the GUI is provided below the rear IR signal generator 172.
  • The universal remote control device 10 further includes a magnet 190, which is shown in phantom in FIG. 5. The magnet 190 is disposed in the housing 14 adjacent to the rear wall 44 and nearer to the lower wall 20 as compared to the upper wall 16 of the housing 14. The magnet 190 is used to properly position the universal remote control device 10 on the charging base 12.
  • With reference back to FIG. 1, the charging base 12 includes a casing 210 having a recess 212 for receiving the universal remote control device 10. The charging base 12 is used by the final purchaser of the universal remote control device 10 to charge the rechargeable battery 66. Even though the universal remote control device 10 includes first and second data contacts 138, 140, the charging base 12 is devoid of any data contacts.
