| 20100013810 | INTELLIGENT DIGITAL PHOTO FRAME - A digital photo frame (DPF) includes a power source, a display panel, a light detector, a motion detector, a processing unit, and a power management unit. The light detector is configured to detect the ambient brightness. The motion detection unit is configured to detect whether anyone is around. The processing unit is connected to the light detector and the motion detector. If the motion detector detects someone is around the DPF and the light detector detects the ambient brightness is below a predetermined value, the processing unit controls the power management unit to provide power to the display panel. | 01-21-2010 |
| 20100026505 | DIGITAL PHOTO FRAME WITH BATTERY INDICATOR - A digital photo frame (DPF) capable of indicating battery is provided. The DPF includes a light-emitting diode (LED) unit, a battery, a battery detection unit, a processing unit, and a display control unit. The battery detection unit is connected to the battery and is configured to detect the charge of the battery and output a low battery alarm signal when the charge of the battery is below a predetermined value. The processing unit is connected to the battery detection unit, and is configured to producing a control signal when receiving the low battery alarm signal. The display control unit is connected to the processing unit and the LED unit, and is configured to control the LED unit to change its display state when receiving the control signal. | 02-04-2010 |
| 20100026914 | DIGITAL PHOTO FRAME CAPABLE OF AUTOMATICALLY CHANGING DISPLAY MODE - A digital photo frame (DPF) capable of automatically changing display mode is provided. The DPF includes a display unit, a motion detector, a processing unit, and a storage unit. The motion detector is configured to detect whether there is someone around the DPF, and produce a display switching signal if someone is around the DPF. The processing unit detects current display mode when it receives the display switching signal and change the display mode of the DPF to a slide show mode if current display mode is a still mode. The motion detector also produce a stop signal when it detects nobody around the DPF, the processing unit controls the display unit to display the pictures in the still mode when it receives the stop signal and detects current display mode is the slide show mode. | 02-04-2010 |

| 20080229103 | Private entity authentication for pervasive computing environments - A method is provided for authenticating an entity having a plurality of keys in a digital form residing on a claimant computing device. The method comprises: generating a first code word by applying a hash function to a first key residing on the claimant computing device; encoding the first code word into an array of bits having a Bloom filter format; generating a second code word by applying a hash function to a second key residing on the claimant computing device; encoding the second code word into the array of bits; and broadcasting an authentication message having the array of bits therein from the claimant computing device. | 09-18-2008 |
| 20090319897 | ENHANCED USER INTERFACE FOR EDITING IMAGES - A digital image editing system and method are presented that allow a user to visualize a range of changes to an image. The system determines a range of parameter values for a parameter of a selected filter. Then, the system creates multiple thumbnails of the image where each thumbnail illustrates a representation of the image with a different parameter value within the range of parameter values of the filter applied to the image. The system displays the created thumbnails in a user interface from which a user can select a thumbnail to apply the parameter value represented by the selected thumbnail. Thus, the digital image editing system allows the user to visually select an appropriate parameter value among the values accepted by the filter. | 12-24-2009 |

| 20080248675 | SHIELDED SURFACE MOUNT CONNECTOR - A shielded surface mount connector mounted to a PCB includes a housing, a plurality of terminals and a shelter enclosing the housing. The housing provides a first protruding portion and a second protruding portion. The first and second protruding portions extend downwards respectively to form a first pillar and a second pillar. The shelter provides a first shielding portion and a second shielding portion for covering the first and second protruding portions respectively. The edges of the shielding portions extend downwards respectively to form a first inserting portion and a second inserting portion. As mentioned above, by inserting the first and second pillars and the two inserting portions into the corresponding holes of a PCB, the shielded surface mount connector is mounted to the edge of the PCB, which makes the electronic products much thinner due to the present invention, and saves more space of the PCB for other designs. | 10-09-2008 |
| 20080299786 | Sucking cover - A sucking cover inserted into an electric connector with terminals received therein includes a sucking portion and an insertion portion. The sucking portion has a sucking surface at the front and a catching surface at the rear. A plane sucking area is formed as a portion of the sucking surface. The sucking surface is parallel with a bottom plate of the electric connector mounted on a PCB. The catching surface is against the top of the electric connector when the sucking cover is inserted into the electric connector. The inserted portion projected from the catching surface has an inserted wall and ribs. While the inserted portion is inserted into an inserted slot of the electric connector, the electric connector can be moved while the sucked cover is moved. In SMT, this action will improve the effective of the electric connector located in a PCB. | 12-04-2008 |

| 20080299835 | AUDIO JACK CONNECTOR - An audio jack connector includes a housing and a terminal group. The housing has an insertion hole extending inward from the front of the housing. The bottom of the base defines at least one signal terminal recess and an auxiliary terminal recess, a first aperture is defined in the bottom of the auxiliary terminal recess and communicates with the signal terminal recess. The terminal group has at least one signal terminal and an auxiliary terminal received in the signal terminal recess and the auxiliary terminal recess respectively. The signal terminal has a contact portion projecting into the insertion hole and an elastic portion extending from the end of the contact portion. The auxiliary terminal has a transverse fixed portion and a first connecting portion extending upward and then longitudinally from one end of the fixed portion. One part of the first connecting portion is jammed in the first aperture, and the other part of the first connecting portion projects into the signal terminal recess. | 12-04-2008 |
