Patent number: 10602275Abstract: Enhancing audio content based on application of different gains to different frequency bands of an audio signal is disclosed. Audio information contained in an input signal can undergo beamforming to provide an initial adjustment to the audio information, e.g., noise reduction, etc. In an embodiment beamforming can comprise double-beamforming in which first audio information is adjusted based on second audio information and the second audio information is adjusted based on the first audio information. Different gains can be applied to content in determined frequency bands, resulting in an amplified signal. In some embodiments, the gains can be related to hearing sensitivity of a listener, e.g., via a hearing sensitivity model. The amplified audio information from each frequency band can then be recombined. The recombined signal can be level limited and subjected to further digital and analog gains. The resulting output, e.g., enhanced audio, can be individually adapted for a listener.Type: GrantFiled: December 14, 2015Date of Patent: March 24, 2020Assignee: BITWAVE PTE LTDInventors: Siew Kok Hui, Lei Tu

Patent number: 10539646Abstract: Remote monitoring of an area with a remote sensing device (100, 200, 300) encased in a rubber ball (302) is provided. A remote sensing device (100, 200, 300) is provided which receives a spoken description of a location of the remote sensing device and stores the spoken description as predetermined location information. The description can be received directly prior to deployment or wirelessly transmitted from another device (400). The remote sensing device can sense information related to its environment via a motion sensor (314), such as whether an intruder is located within a vicinity of the remote sensing device (100, 200, 300). The remote sensing device (100, 200, 300) can then transmit the predetermined location information and the environment information to the another device (400) in response to the sensing. In response to receipt, the other device (400) can render the predetermined location information and the environment information in an audible format.Type: GrantFiled: June 29, 2017Date of Patent: January 21, 2020Assignee: BITWAVE PTE LTD.Inventors: Siew Kok Hui, Chu Guangzhi

Patent number: 10425736Abstract: Boomless-microphones are described for a wireless helmet communicator with siren signal detection and classification capabilities. An acoustic component receives an audio signal and comprises a left acoustic sensor and a right acoustic sensor. The left acoustic sensor is mountable or attachable to the surface of a left wall of a helmet and the right acoustic sensor is mountable or attachable to the surface of a right wall. A speaker component can generate an echoless audio signal via signal inversion of the audio signal, outputs to a left speaker mountable or attachable to a left ear area of the helmet and a right speaker mountable or attachable to a right ear area of the helmet. A signal enhancement component can increase an intensity of the first audio signal associated with an emergency siren based on a determined proximity of an emitting emergency vehicle or emergency object to the device.Type: GrantFiled: June 30, 2017Date of Patent: September 24, 2019Assignee: BITWAVE PTE LTD.Inventors: Siew Kok Hui, Eng Sui Tan

Publication number: 20190158964Abstract: With regards to a hearing assistive device, a user's speech can be picked up by the microphone and feed through the speaker causing an acoustic feedback effect. The user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Furthermore, the when the hearing assistive device experiences feedback, the amplification of the feedback can cause damage to the user's hearing. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device. The acoustic feedback can be mitigated by leveraging a dynamic range controller and a howling detector which comprises a user interface and a status indicator.Type: ApplicationFiled: January 18, 2019Publication date: May 23, 2019Inventors: Siew Kok Hui, Lei Tu

Patent number: 10255775Abstract: Motion or event detection and notification devices and methods are disclosed. Motion or event detection information can be processed and interfaced with in order to facilitate system functionality. In an embodiment, a unique ID can be utilized to identify a recipient of an alert. Unique IDs can correspond to different users or devices of a motion or event detection system. In some embodiments, information relating to the detection can be relayed to a user of the system. That information can take on different forms, including basic information such as a simple notification or other forms such as a live feed of the event. The ability to implement such a system can allow for increased security for an area or increased peace-of-mind for a user or monitor of the system.Type: GrantFiled: August 22, 2017Date of Patent: April 9, 2019Assignee: BITWAVE PTE LTD.Inventors: Siew Kok Hui, Eng Sui Tan, Man Tuck Pang

Publication number: 20180160239Abstract: For many hearing assistive devices, the user's speech is received at a larger amplitude signal than the speech of someone speaking to the user. Since the user's speech is also picked up by the microphone and feed through the speaker causing an acoustic feedback effect, the user may have to constantly adjust the volume of the hearing assistive device to achieve a more comfortable volume based on where the speech is coming from. Therefore, mitigating the acoustic feedback effect of assistive hearing devices can generate a more efficient and comfortable hearing device.Type: ApplicationFiled: February 1, 2018Publication date: June 7, 2018Inventors: Siew Kok HUI, Lei TU
